Hi Folks,
Pretty new to electronics just a pretty simpe question...
Does anyone know of any very high end non polar audio caps (around the 22pf - 33pf) range (Polypropolene???)

Plus are Vishay (Polypropolene) orange drop caps non polar???

Thanks.

Mix.....
 
Yes, the orange drops are non-polar. www.diycable.com stocks some caps that will get up in to your range (polyprops) designed for audio, or you can search for any non-inductively wound poly caps in www.mouser.com. Solen, available from www.partsexpress.com has polyprops available in large sizes, and www.angela.com has poly in oil caps in that sort of size, IIRC. Also search ASC oil for large motor run caps on ebay.
 
Well, IIRC, they're non-inductive (or at least largely so) so that's good for the audio purpose, but as to how they sound, you've got me, I've only used them for their intended purpose and in power supplies. Input caps are frequently so small, I'd be inclined to go with a known good..... in my own tube pre, I used a 10 nF silver mica, which are excellent for audio, when they fit.
 
Hi, forgive me for hijacking this thread, but recently I read something on these forums about a recommended way of wiring Black Gate non-polar caps (long lead or short lead to ground). Can anyone point me to the correct way?
Cheers!
