Thanks Irish
I have talked to him knows his stuff.
How does North Creek compare to others? (ex Duelund) Big improvement? |
Ait
So does that make the Duelund WPIO inductor better in the sense that it is wrapped in paper? There must be less interference?
Irish65 I wish you could say what you thought was better about Duelund or why you thought it to be that way? Your opinion could mean a lot as you have tried many components. |
Thanks Duelund
Sorry just one more question are all CAST inductors 8AWG I thought they were 12AWG? Is this a special case?
The WPIO are not done under vacuum for 5 days are they? Are you talking about the CAST inductors only?
My choice (budget wise) was your WPIO or another brand. (not that I would not want CAST)
I have never replaced a woofer inductor and can clearly hear what the CAST does on the tweeter caps but is it my pig headedness that thinks that a low freq inductor would not be as critical to resonance? |
Ait
Now if I had a livingroom system that would be different. Mine is a basement system.
I had a livingroom system at the start of this thread but the ugly vintage system with the Duelund caps and vintage tube amp smoked my new gear so bad I sold it. (still have what was a fully loaded LP12 from a few years ago) The new gear won the beauty contest but that's it! Interesting how so much stuff goes overseas now. 1 amp went to Russia pre amp to Thailand. Only the speakers went local and one amp to Michigan. |
Irish65
As you have mentioned you read a ton and then just started buying the parts. I would love to hear what you found out?
Clearly you have valuable experience to share. Most of us may not ever hear CAST AG caps or whatever else you have found out. In your upgrade path clearly you must have been thrilled (or something kept you going) with what was happening or you would not have kept going to better/more expensive parts? Like what was the most important upgrade and most cost effective. In your experience you must have that some parts were good some great and some good for the $ involved. I would imagine many would love to hear. It is no doubt part of your recommendation (and others) that I have tried North Creek.
Have you done coupling caps? |
Irish65
That is good to hear about Duelund's consistent sonic signature. (for inductors) From what I have heard (VSF and CAST) they sound similiar you are paying for a huge reduction in resonance.
That was the reason for (me) getting 10AWG North Creek less up front money.
My inductor comparison will involve only 2 at most. The other being Duelund's WPIO.
I totally agree on the crossover as the heart of the system. Something I never would have thought before. |
Thanks Duelund
I am very excited to see what the VSF does in the DC signal path. I guess that the VSF is coming over in your next shipment at the end of the month? .047uf.
So far every Duelund part has preserved the "live" feel well reducing noise and giving better tonality. |
Sherod
Either cap is great. I think the VSF are a good deal in audio. You get a plastic free super natural sounding cap at yes somewhat more than other caps like twice Mundorf Silver in Oil. But to me worth it. If it is any consolation I marvel at the sound of them and have long since forgot what I spent. (and I do not throw money away easy) Have you ever thought about trying just one cap like the tweeter cap to see if it is worth to you.
I started with one cap thinking the worst thing is I was throwing away $150 or so. I know if someone said to me you are going to have $2k (in just caps) in the crossover I would not have done it. (I know I would not have done it) When you start small you can get a better mental handle on whether it is worth it. |
My one amp that is slow as ever getting back, my tech guy says he needs a 40uf, 40uf, 10uf 10uf all 450 volt caps in a can. Any advice on brand or where?
Thanks |
Ait
Is 4 separate caps a better way?
When Mundorf sells a 40+40uf is that the same as 2 40uf's? |
Ait (everyone)
Can you give me an idea of what the difference is on a good power supply cap? Just more power reserves? Less noise?
Do power supply caps weaken or just blow? How do vintage compare to best ones today? |
Tempo Electric says that ASC is the best in the power supply. They sure are massive! Is that a good thing? |
Thanks Dave
Might be out of my budget and league. I just went off the Tempo review giving the ASC X386 Tier A. I am going to rebuild all of my vintage amps if this works out. For at least safety reasons.
What do power supply caps sound like when they go bad or do they just blow up?! |
Thanks Ait
That was the issue why the guy fixing it was taking so long. He could not find ones that fit into the can.
These of course will not fit in the can. That is an issue to many. The look thing and height thing to go in the case. My amp is not in the case and I do not care what it looks like. So I understand they can be wired under or on top?
An amp like yours which is nice looking is one thing. To me vintage amps (most of them) are ugly. So if holes need to be drilled or whatever so what. As long as it works.
I guess something like this pic.

Looking forward to hearing what a large guage (10) low DCR inductor means.
Also looking forward to what Duelund hook up wire will do as well.
Looking forward to see what power supply upgrade does.
But the main one I am looking forward to is coupling caps.
I am going to try two caps V-Cap Teflons and Duelund VSF.
According to Peter Qvortrup “ It is becoming increasingly obvious that applying transformers at every stage of an amplifier yields a great benefit in sound quality, provided of course that the transformer in question is of an appropriate quality and design. Replacing any coupling capacitors with a well designed and correctly matched driver or interstage transformer yields an almost shocking improvement in sound and should be tried to fully understand what a good wideband transformer has to offer. ” Peter Qvortrup
http://www.audionotekits.com/monob01.html
Does this mean that coupling caps are a great area of weakness? |
Sherod
That was funny!
I was talking to a guy here who used to own two Stereo stores and said the output transformers are like wine and that they get better with age?
Anyone care to speculate how that happens? |
ASC caps arrived today.
Holy Crap they are big! I knew they were big but Holy Smokes! |
Face I agree with you expensive experiments indeed. (but the yield can be equally rewarding)
My speakers are not good for soundstage anyway so that was not an issue for me. Tonality, timbre and dynamics was what mattered for me. Now I could not give that up. I can't say how many times I can tell what the instrument is now that I had no idea.
If Duelund VSF Copper (not heard Aluminum) had a weakness against other top poly caps they may not be quite as quiet. The CAST being designed for horns certainly are but I would have no idea how they compare on a soundstage basis. |
ASC power supply caps.
They are made by Jensen. I may have been the only one not to know that.
I read somewhere that Angela Jensen and Audio Note are all exactly the same. Is this correct?
Duelund I read on Tempo you had 630v caps yet parts connexion says only 400v? Can you fill us in? |
Face I just got an e-mail from Parts Connexion that beginning today 20% off everything. |
Elviukai
What value of caps? (voltage as well)
Just change your mind on project? |
Parts Connexion is running the sale for another month so I will be getting more parts.
Vintage amp has a weak phono stage. Too noisy. I will be seeing if that is caused by poor (noisy) foil caps in a critical area. I expect so. I am going to start with some Jensen .022uf caps. If that does change the problem I may go to Duelund CAST at some point for the phono stage.
Listening to Ray Charles and Norah Jones and must say Ray sounds much more real. Both good recordings but vintage Ray Charles sounds colourful and alive compared to clear black and white for Norah. I suspect tube recording gear and foil caps in the chain. |
Anyone ever try Audio Note copper foil capacitors in electronics?
I really like the vintage foil caps which are Vishay ERO FOL. I do not want to change the supreme tone. Audi Note is not a fan of any poly caps or Teflon. They say every poly or Teflon caps adds to the sound and at least the cheap ERO caps subtract rather than add.
The one dealer I buy some gear from says the Audio Note sounds smoother than Jensen's?
After listening for months now I just want stick with foil. SNS did not go crazy over V-Cap's, says they have a signature? I keep hearing that and that does not inspire confidence. 400 hour break in is not fun either! Also remember what one poly cap did in the crossover killed the whole sound.
I will try some Duelund in areas of room and critical circuit.
Power supply being done this week. Looking forward to that as well |
For months I have been confused. As soon as a 50 year old tube amp pulverized my $10k SS amp and pre I have had to know why?
Where was the 50 years of progress?
Why did a capacitor (Duelund) made of nothing more than copper and paper and natural oils sound wayyyy better than any new tech poly cap I tried?
Why did this vintage amp sound so good after all I have heard some of the most exotic new tube amps? I admit I have only heard the tube amps through speakers running poly caps and as I already found all it takes is one to change sound. One of the speakers was Dynaudio which I heard but do not know for sure use Solen caps. If they do how could any amp sound good through Solen's?
Stereophile admitted to vintage being very good with no "audiophile" parts and NO advertising money coming to the magazine. Why?
I thought the vintage amp had foil caps but I think it is metalised polyester I have been told. (from someone on this thread) Audio Note use Vishay ERO in their Level 1 amps. The very same as the vintage amp?
A quote from Peter on the Audio Note website "In all our Level One amplifiers, such as the OTO Phono Push Pull, we use the green ERO MKP metalized polyester capacitors, these cheap and cheerful industrial capacitors have been chosen through extensive listening tests against practically every commonly available polypropylene, polycarbonate, polystyrene and polyester capacitor on the market. They are far from perfect, but from a sonic standpoint they are purely detractive, meaning that they lose information rather than add it (which every polypropylene, Teflon etc. capacitor I have ever heard does to excess)".
Is that why the vintage sounds so good? A fluky good cheap capacitor?
Tony Gee seems to like them? Though he thinks they are poly? Audio Note says not? |
Dave
I have one Mundorf Supreme Silver in Oil and I understand they can be tied into the power supply as a bypass cap? Anyone ever try that?
It would be with the all ASC caps. I figure might as well use the cap. |
Ait I think the voltage is 800VAC. Mundorf's are not really a oil cap. Know do they sound good there I have no idea? It is just sitting here so I thought I might as well use it. |
Undertow Your results seem to concur with Tempo Electric who rates the Solens as Tier B with the Mundorf Supreme and of course cost much less.
I only have that one Mundorf sitting here that did not sell the rest did.
I am rebuilding right now to ASC caps (only because of what Tempo said Tier A and not that expensive) in the power supply for two reason the Electrolytics could be done anyway and am very curious what top notch power supply means?
Duelund has been a blessing and a curse. They sound fantastic but makes you start to think and that costs money!
What does a good air core inductor mean? (which I hope is here today) Then it is what does top notch coupling caps mean? What about Duelund wire? (which I hope is here today as well)
Undertow have you ever tried a full poly (Solen) power supply? So what does even bypass mean as far as sound? |
Sorry Duelund
I am sure you will get another mate to the inductor.
I just want to be sure it sounds right. I probably should have just ordered two but last time after I heard the VSF I ordered CAST.
Are you getting into Autoformer's? I seen on a website what looks to be transformers coming? Would it be a simple process to make an Autoformer the same way as inductors?
I might be interested in one of those as well. (or should I say two at some point) |
The North Creek inductor is here.
Like all of you guys I am trying to get the most improvement for the $ I have or am willing to spend.
I actually like it when someone says your nuts. It keeps you in check. I agree with Dgarretson that a system is only as good as the weakest link. I have tried to go after those right away.
I choose Air Core low DCR inductor as this was talked about by Steen as area of importantce. Since I had Iron and maybe some corrosion and a higher DCR I am expecting improvement here. Just not sure how much.
I also choose to fix the power supply in the vintage tube amps as they are likely worn anyway. So again going from Electrolytic and possibly/probable worn (meaning going bad) another area of weakness to top notch poly power supply and maybe even adding some uf's.
Another area is Klispch used lamp cord wire back then and cheesy guage. So I have went to plastic free Duelund and heavier guage. So possibly corrosion and for sure not good quality to beging with. So again I am hoping for some improvement. But also a area that is not a waste anyway.
So guys feel free to shoot down my thoughts and say something like you should dump the old amp. Are not basic tube circuits pretty much the same? Just parts quality they are done with?
My thoughts are getting a new/newer amp with a top notch power supply and top notch coupling caps would not be cheap either.
For about $1500 or so you can have either all AN, Jensen, V-Caps in coupling and ASC in power supply good vintage tubes etc. To me I would think that would sound very good for $ involved and since looks are not a factor what do you think? |
Undertow What is that proceed with caution. You almost say that like you have had something explode?
The ASC at 4000uf do you mean 40uf? Confused?
North Creek inductor is huge. The size make the original look like a toy. I do not know what that will mean to sound. Should be interesting. |
In one of the amps I bought had Mullard's in for EL84. I had no idea they were that much money. They sound awesome!
I almost feel quilty using them.

Undertow
I should say I am not playing with the power supply. (that kind of work is over my head) I am having it done by a guy who has worked on tube gear his whole life.
Installed the North Creek 10 guage inductor.
It is as I suspected not going to be near like the tweeter cap change.
George at North Creek said the biggest change I would notice would be in the midrange. This is not what one would initially expect from a woofer inductor change.
I suspect that is a reduction in boominess (because of no hysterisis) and lower DCR allows the midrange to sound cleaner?
Bass lines are easier to track but the midrange become too prominent. More detail yes, hearing things I never heard.
I have this theory on resonance. We are used to it many systems. Lots of it. When friends came over when I first had the Duelund VSF tweeter caps in for the first half hour they would all pick the vintage tweeter caps. (I did not tell them which speaker had which cap) then after half an hour on each speaker going back and forth they would all say what's wrong with the vintage cap speaker? You can't hear anything just a blurr. Then they just could not believe the difference after awhile but at first they did like lots or resonance.
In this complex relationship between drivers is where speaker designers earn there money!
One speaker has (and this is on purpose) vintage inductor, VSF midrange cap and CAST tweeter caps. The other speaker has VSF tweeter caps, VSF midrange and North Creek 10 guage inductor.
You would not believe these were even the same speakers! The difference is enormous!
This is very complex stuff!
The CAST set one lots of bass warm with great detail and balance. The VSF/North Creek thinned out but even more detail (caused by 10 guage indcutor) but too much emphasis on midrange.
The CAST in the tweeter caps cuts noise by a massive amount. Oddly enough the tweeter cap seems to cut midrange output.
I expect that the best combo will be (that I have) the North Creek inductor with the CAST tweeter caps. |
Inductors must break in like caps? Starting to sound much better already?
Sorry about post but I actually do that for myself to read back on initial thoughts. |
Ait
I believe you are right as well. I believe the ones Steen was talking about are these at Jensen?
https://audio.jensencapacitors.com/products/capmetpape/?crumbs
I think polyproplyne would be very good in the power supply. Even as one who does not like them in the signal path poly is very good at doing one of the two things caps do and that is getting out noise. I don't care for what they do to the signal but of course they are not in the signal when in the power supply.
I have been giving more thought to Paul Klipsch's inductor. It is not the standard steel laminate inductor that we see most often but a upside down M. I wonder if metal on the outside is to stop stay magnetic field? In my tweeter circuit the resonant trap is air core wax paper inductor. So he clearly knew of the "benefits" of air core but did not use it? I know most would say for cost reasons (which could be true) but this was not a cheaply made inductor like many of today's? He could have not done a M and no wax paper to save even more money.
In the Klipsch post I copied in Al Klappenberger was shocked at how little distortion the metal core had? He had believed Air to be much better.
Another guy in the post talked about using a large inductor and being able to disconnect the tweeter and only lost 20db of output! That is clearly NOT good. In fact to me that sounds like what is going on. My mids and highs sound rough with new inductor?
Haven't had a chance to check but it was mentioned here before of surprising level of cross talk. Paul K has gone to it seems great effort to stop that.
I am going to do some more tinkering to see what can be done. |
Hysterisis I have read about it but what does it mean sound wise?
The vintage inductor is iron core wrapped in paper and wound around the core is wire wrapped in paper.
Some say hysterisis is almost like the plague.
From the Klipsch forum interesting read and not would one would think.
http://forums.klipsch.com/forums/t/38976.aspx
One thing inductors matter more than I thought and not where I thought or in the way I thought.
The vintage is muddier sounding in the bottom end (maybe the higher DCR) yet so far is smoother through the midrange?
I have set the North Creeks on cardboard because I sense ringing? This seems to make the voices rough. One of those things that give more detail but does not add up to more enjoyment? I switched to Audiophile CD's to make sure the inductor is not revealing CD player weakness. In the bass the North Creek is better but might come at a price.
The North Creeks might smooth out as well after all just a few hours. Sounds for sure are crisper and sharper. Piano on the vintage sounds like a blanket is over the piano. The North Creeks though give more HF noise without a doubt!
I did not expect this?
Irish65 I think I know what like about the North Creek's and what was likely better about Duelund that you could not put your finger on. This comparison is going to be very interesting.
For most Klipsch guys that have not replaced your inductor I am not sure I would waste my money. I bet many of the modern inductors with no paper sound wayyyyyy worse than what you have.
So far the vintage is better. The trade offs are much better. Smoother voices more dampening less ringing less of a stark sound. The vintage gives up some detail.
I have wired the speakers up the same to eliminate the caps having any effect. |
I just got back and was thinking just what you said Ait. (crosstalk)
I have lots of space should the inductor be as far away from the tweeter caps or the tweeter?
It was you who mention this awhile back when you got a big North Creek inductor, right?
It almost sounds like LF being sent to the incorrect drivers?
Face you could be right as well, I was thinking that might happen (DCR is cut in half) except the signal sounded distorted not just off balance?
Undertow I have had good luck (real good luck) on the parts switch when staying to the same type meaning switching out a Aluminum foil in oil for Duelund Copper in Oil. (better in every way) The problems are when the poly cap goes in the network designed for foil.
Thanks guys I will do some location switching on the coil to see if that is it. |
Undertow
I am not looking for a miracle cap.
But what if the there is a reason to wrap the inductor in wax paper? What if Mr klipsch knew something?
Most people agree Duelund makes great sounding parts. What's "new" about them? Paper, copper, cocoon silk and natural oils have all been around for 100's of millions of years!
Yes the North Creek is a monster of an inductor but it does use varnish. There is no paper and no dampening between the wires. In defence of Frederik there is clearly a difference in time of construction. I hoped (in a strange way) that Frederik is just being obsessive and I could not hear what his paper and oil does. (for cost reasons) I did tell Frederik the second best cap in the mid range (I tested) was the original Aluminum foil in oil (wayyy better than all the rest) and in fact I would love to hear it compared to Duelund's (Aluminum) because I bet I may not tell the difference. |
Undertow
I thought you owned Khorns? You will be glad to know they sell new in Europe for $20k a pair. Those will not come with the Alnico magnets though just the cheap ferrite ones. I seen in a British Audio Magazine a set of 30 year old Lascala's for 6,000 pounds or $10k U.S.. Yes I know they go for nowhere near that here. I am sure no doubt the SET crowd is bidding up high eff speakers across the pond. |
Now I find the article Steen had wrote on inductors?
I believe the vintage is Steel Laminate wrapped in wax paper.
http://www.meta-gizmo.net/Tri/speak/jenson.html
This does have my hopes up though of the oil filled power supply caps. Steen was a fan of oil in the power supply.
I am going to try some Jensen paper tube caps .02uf in the amp in the sizes that Duelund does not make. I have learned enough lessons on this stuff and was glad to hear Steen liked the oil power supply and it is made by Jensen.
I am going to move the inductor up to 10'away from the speaker and see if that helps if it still sounds hard does anyone want to buy a never hooked up inductor?
|
Dgarretson
You might be right (sound wise) but I am unsure on the existing electrolytics. They are old and and this is partly safety. I have heard many horror stories on blowing up electrolytics.
I am very excited about oil power supply.
One thing Duelund caps have done is reveal amazing tone but will show any upstram weakness. The EL84 amp I have is amazing until things get tough. I suspect the power supply to weak and maybe coupling cap.
I am not mad at all about the Indcutor it has made things very clear to me on what an inductor is and what they can do. I have not heard the cheap inductors like Solen. SET over on AudioKarma had compared Solens to North Creek and found North Creek much better. This does not surprise me. Solen from Parts Connexion pics looks like loose wire? I would expect sloppy sound out of that. The North Creek is like a rock and in my opinion sounds hard very great detail and could be a great inductor IF it was wrapped in something like wax paper.
What I always find surprising is that we always assume today's stuff is built better? I could make a Solen myself get a core some ties wrap the wire around the core and voila an inductor. The North Creek is at least baked for hardness. The supposedly antique vintage inductor is 28 (an exact number) pieces of laminated steel in a steel housing. Then they use a cardboard around the steel then wax paper making the whole inductor hard as rock. I could not make that! If one wants to see a cheap inductor my new Linn speakers had a piece of wire wrapped a round Iron core which one could do in 5 minutes tops!
http://www.partsconnexion.com/t/catalog/inductors.html
Here is a pic of a 1968 set of Sony's the owner says sounds good. I am not surprised air core inductors wrapped in wax paper. Hmmmm? Tell me how a new modern Solen could be better? I bet I can guess why there is not wax paper anymore on most inductors? Hmmmm? Frederik even said it takes 1 minute to manufacture some inductors. North Creek longer as at least there is some hardening.
http://www.agoraquest.com/viewtopic.php?topic=32527&forum=51
I am so glad I have done this experiment. I have said to Frederik the vintage Aluminum foil in oil midrange cap I bet is a good as his which cost $250 for the midrange alone each! My whole parts costs on the $5k Linn speakers (and they are no different than most manufactures) would be $30 or $40 for both speakers. |
Well George (North Creek) was right. You will notice the inductor mostly though the mid range. Not what I would have expected.
The not so good part is the vintage is clearly the better inductor! Much smoother in the mid range the back ground is much blacker as well and there is much better separtion of instruments. Much more musical sounding.
The wax paper is not there for no reason!
The Duelund WPIO is $429 each and this is out of the range for me. I am unsure if or how much better it would be anyway?
The vintage inductor sounds better than the $150 North Creek and could be worth (in new prices) somewhere between $200 or $300?
I was thinking of replacing the parallel tweeter air core wax paper inductor and am not going to do that (at least for a long time) as only a Duelund WPIO (or similiar like Jensen) would be the only one worth it. They are almost $200 each.
I feel with Jensen and Duelund caps in the amp is a better place for the $ right now.
If I could only find out for sure that they were Aluminum Foil in Mylar caps. No one seems to know what they were? |
I have been reading some Audio Note stuff and the only thing that concerns me about spending money on a old amp is I have not heard as SET amp. (Dave says I have the speakers for the amp 104db)
I love this quote from AN artice. I am wondering if my amp is not old enough! After all SET is older than EL84.
"To my astonishment, the most successful products at coping with “Comparison by Contrast” were more than 15 years old (in 1980, that is!) and the further back I went the better some of the products, especially the amplifiers, turned out to be". |
Any of you guys switch from Push Pull to SET and what do you think?
An area I am thinking about in the future. |
Duelund copper hook up wire is here as well as Mundorf solder.
The Duelund has this kind of natural smell to it like the caps do. The VSF caps to me smell. A good natural smell.
Duelund what stops the oil from drying out? |
Face 60uf!
That must have been a special order? Have you hooked them up? How do they sound? Replacing Electrolytics or poly caps? |
I am going to order a VSF .047 (400v) and Jensen .022 Copper paper tube.
Honestly, I am ready to throw in the towel and say Ok Frederik you win.
The only reason I am trying the Jensen is Duelund does not list .022. But Face if you got 60uf they must make to any size? Seems so expensive for .022 as well! |
Face
The first caps I put in were Sonicaps compared to the vintage foil in oil. I did one speaker with each type. I then got my wife to come down and here the difference. (she had no idea which was which, so completely blind)
She said "Clearly that one is wayyyy better. This is the best thing you have ever done" (audio wise) She was very impressed!
The only problem was the speaker she thought wayyy better was the vintage one!
I just paid the $ for the caps and an hour or two farting around to install them and after 30 years of wear and new technology the old foil caps were wayyy better?
She said they sound like real people and real instruments. At first I was impressed how much quieter the Sonicaps caps were. The noise floor was MUCH lower.
What I mean by all of this is that (tonality) is what you are getting (and paying for) with Duelund. Once the Mundorf Supreme's went in they were as dynamic as the foil caps (much better than Sonicaps) and as dynamic as Duelund but everything sounded still like plastic.
Now is that worth it to someone?
Tempo Electric says "A clear improvement over the runner up. Brass instruments sounded more like brass, violins sounded more like violins, and so on. Everything was cleaner, smoother, and exhibited less glare. Previous to installing the Duelunds, we thought the (now) runner-up was so good that we didn't recognize its flaws until they were gone".
Tempo was correct to not say they are more more dynamic or blacker backgrounds.
I do think foil caps are very expensive as well. Tempo also says of the Jensen's Aluminum foil in Oil that they are Tier F! That is not cheap for a Tier F cap either!
Jensen coppers were only Tier D.
This is where I am having a tough time Tier A V-Caps are fairly cheap. Tempo has not tested Duelund or the new Jensen Paper tube in oil, and I hate wasting money. |
I can say inductors are wayyyy more complicated than DCR and Iron or Steel or air core.
There is resonance there as well. The more I hear the more respect I have for PWK. I paid $150 for the NC and would pay at least $200 or $300 for the vintage one. MUCH less resonance.
There must be some kind of interaction in the coil with the rest of the coil? I get a high freq noise. Is the coil vibrating? Before I bought this I would not believe 10 gauge wire could resonate?
I have moved the inductor much farther up the list of purchases. In my rebuild I am leaving room for a future Duelund WPIO. In the meantime the vintage in is VERY good in comparision.
IMHO tread lightly in inductors lower DCR is not all it is about.
Once again vintage parts could be a real alternative to modern parts. I expect the vintage inductor would beat any inductor barring maybe another wax paper inductor.
I just finished selling my plastic coated Linn k-600 tri-wire this week. Looks like a inductor will be next to go. |
A heavy hitting cap review oming. Pretty well the best of the best.
http://jimmyauw.com/2009/06/13/be-prepared-for-extreme-capacitors-battle/ |
I may have egg on my face.
I swithced amps to see how the inductor sounded on a SS rectified tube amp. Sound is very strange? The vintage is inductor very choked off? The North Creek volume is much louder?
I still can not believe the difference from one inductor to another? I have to admit I did not expect this!
One too muffled and choked the other to hard sounding.
I thought inductors would not show much difference as they do not age like capacitors. (as far as I know)
I am going to sell this just yet to give more fair comparisons. |
