FUSES, Finally!?

     I have been adamant about avoiding special fuses, because of the lack of empirical studies.  Here is my question:  What would be something not too expensive that would be a good start.  I use three dual mono Audire amps (for Woofs, Mids and Tweets, and Subs, each of the six channel having four fuses.  I would not not want to spend thousands, even if I could, just to experiment.  My heat sinks do unplug, along with the outputs, and I could try just one channel or one amp.  Paul of PS mentioned what they use, and that might eventually be a possibility, but what do you guys (and gals?) think I should do, to just to convince this ageing skeptic?  Also, each channel of my amps has one single, dedicated computer chip that regulates the filling of the 4 26,000 mf caps (per channel), which might make any difference less than a design that allows a flood of electrons into the tank, presuming that might matter.  DanV

It's simple if I was down under I'd have George fix my stuff If he had the time.. I can always sneak in my fuse later.. I'm sure he's quite handy in the troubleshoot and repair department.. And what George likes, all weigh a TON.. I like tonnage in speakers and amps.. just not on the back of the old flathead. 115 is about it.. Tire rubs.. :-)

What I find funny, is there is a lot of truth on both sides of this silly argument.

A simple fuse pull and reverse the direction after 20 or so turn ons.
IF you can hear a difference, chances are a fuse change will change the sound, (FOR YOU). If you don’t save your money. Clean the fuse pocket, check for any ARCING and replace the holder if there is.

I found the same thing with power supplies. The physical mounting and dampening of a chassis, night and day. The quality of the power supply. I found that PS that have WAY to much in the way of filter caps are a SUPER pain in the rear. For surge cold starts.. I had one pair of mono blocks that were tough to start. After you threw the power switch you, lifted the knife edge bypass, the fuse was all that was left in the circuit.

Once started, NEVER had a problem.. They were modified and built by a guy named James Bongiorno. Gas M Giant (mighty not mono block, he would say). Those things had a circuit breaker in them too. I had 1 pair of 4 or 6 ever made. 40 years ago maybe.. I don’t think they ever saw production.. Pimp Daddy.. That’s what they use to call the dude.. Good on the keyboard. Jazz fella.

So I have seen a fuse make a difference in power amps for valves, more so than SS. Chassis dampening, I use a Cary V12r. That is one of the quietest chassis I’ve EVER used.. Almost like pot metal it’s so thick..DEAD quiet.. High temp, med soft silicone mounts for the transformers.

The Cary likes SR orange or blues. My Mark L.. they could give a hoot.. My Brain 565s, they could give a hoot, Nord NC500 with stock fuse holders, they could give a hoot. My Macs MC225-275.. LOVE SR fuses...My C2500 could give a hoot.. My MX120, loves ONE fuse the rest inside could give a hoot...(4 total). My Sony ES SACDs LOVE SR fuses. Most of the TT stuff, they don’t, that’s right "Give a hoot" The RtR I haven’t listened. BUT I bet it makes very little difference, GREAT PS and the IC just serviced..

SO THERE.... The Hoots and Hoot nots. You all need to learn to "Ponder" just a bit.

Mr cakyol, Do not believe the superhumans?

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>

I do believe in being respectful, and understanding others can do things better than me.. Paying attention to detail. Being able to run faster, type faster, talk faster, listen BETTER or have better hearing, in spite of what I can or cannot hear.. I still respect the fact others are BETTER... I guess that is tough for some folks to hear... They can’t hear the difference.. I’m glad when some one can.. My heart doctor in particular.. :-) GOOD set of ears on that guy...

ttocs12699 posts01-22-2021 6:42pmif you use a power conditioner/surge protector could you just remove the fuses?

<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>

NO.. Fire protection, and equipement protection first.. You can get in trouble if you’re not careful.. Usually there is a 2-5 amp slow blow to get a valve amp going and a .5 -1.5 quick blow, for a tube failure..

LOL I’ve bypassed fuses and really seen an improvement too. It usually had to do with low impedance loads like 1-2 ohm loads and BASS drivers.. Me pushing amps for all I could get, before big class Ds..

Purple Haze, was LSD of old.. Hee hee. YUP... Now it is a variety from the "Haze Brothers" and "Super sativas". These were and are REAL things..

As for the fuse bypass.. I’ve never had a problem.. BUT I do take precautions. NO I don’t recommend it, I’ll keep my sonic nuggets to myself...

SS is tough enough to make sound right, without fighting a stupid fuse and a power cord. Talking about James B.. He welded his PC in.. he wanted you to use HIS PC.. Welded, is what they state, not solder a # 12 cable.. Why only a # 12?.. YUP, there is a reason for that too.. It is a certain length too..WHY? All part of the PS design. Smart dude.. Liked Single malt Scotch too.. :-)
