crimping vs soldering
Done properly, crimping wins hands down. That means the correct tool for the crimp and a ratchet type crimp tool (in good condition), so the tool will not open untill enough pressure has been applied.This produces an air-tight cold weld, which is ... 
Vintage turntable running fast, any ideas?
Hi fi is usually a bottomless pit - but have you ever noticed that most musicains listen to things with the sonic elegance of a mice powered turntable using a 4" nail hooked up to an old tin can with a bit of string? 
Need help : Single ended, Low power, SET amps..
Hi Tweek,Believe it or not, I didn't say JBL just because they are so efficient. Most hi end people consider the JBL sound is what you get at concerts. Well sometimes it is, but how would a whole wall of your favourite hi-fi speakers sound, often ... 
NOS Tubes inferior?
6922? Bad luck! The dutch made Bugle Boys thrash all current production soundly, even given that yes, glass is porus to (mostly) low molecular weight gasses such as hydrogen and helium - fortunately present in low concentrations.What will realy st... 
Need help : Single ended, Low power, SET amps..
Try looking up the triode guild on www.meta-gizmo.com. Eccentric, irreverent, thought provoking and informative if you can cope with an intellegent very anti pollitically correct approach that is not as sexist as it appears once you get past the s... 
Tube amp in a hot weather: Does it require a fan?
Tube coolers by Pearl will help both sonics and tube life. They are chemically blackened copper fins that push fit over the tubes - only downside is less glow visible!I know Michael Percy Audio has 'em, maybe Partsconnexion or Audio Advisor worth ... 
I'm in the mood to make mods.
All of this stuff is time consuming and presents many challanges to be overcome!The more I've done, the more ambitious I get. I'm presently extending amplifier cases so the power supply I think is good enough can fit - its a 250W mosfet monoblock ... 
Are you a D.I.Y?
Designing can be a tough road to go down, you need to know a lot.There are LOTS of good designs out there.I like to pick up bits of gear 10-20 yrs old and upgrade the parts to modern good stuff like multicaps and caddock. If you like the way it so... 
troubleshooting VTL puzzle.
Look at what Jcbtubes has suggested and if that is not it, I have seen the adjustable pot cause some problems. Check it is the same value end to end(compare to the other ones which are OK) that is along the conductive track - the two outer tags fr... 
Strategies for preserving tube life
My suggestion is to get some Pearl tube coolers and fit them. Not only have I found that they make the tubes last much longer (I don't know how long, all my small signal tubes are still ok after several years use - I switch my amps off at night), ... 
CAN Bi-Amping been done Correctly?
Yes!I have used a tube amp for mid/trebble (passively crossed over), mosfet monoblocks for bass and a bridged mosfet stereo amp for sub, the 3 lots of amps being crossed over electronicaly.I have used a professional x-over with the resistors and c... 
Vintage turntable running fast, any ideas?
You could try wiring an ordinary light bulb in series with the motor - be aware that it needs to be in a safe place as they are reasonably easy to break and of course a broken light bulb is an electric shock hazard - also remember they give off he... 
I'm in the mood to make mods.
So glad to be of some help.I'm totaly hooked on mods myself, nothing in my system is stock, or even near! You can do as you can afford it, you learn a lot and I agree, it is relaxing.It also keeps the upgrade bug at bay because, if you choose some... 
Looking for a cd source for my system.
At this elevated level, listen first! As well as Levinson try Wadia and perhaps Krell. All are good, but you need to find "your" particular flavour.I think anyone with your gear probably knows what they like when they hear it - trust your ears! 
Converting to Analog
GO for it. A second hand table with no movement in the platter at all apart from round and round (sideways rock is BAD). I got a VPI Jr cheap and upgraded it slowly to Mk4 as I could afford it - an Orogin Live modified RB250 arm unless you are fee...
