Not sure what you mean by "best", but these are all reliable, go-to mail order e suppliers.

 

What’s wrong with your SVT that makes you think it needs new caps?

 

I typically suggest to leave well enough alone, unless there is a very good reason for changing something.

(I often see the results of such projects gone wrong and it's usually worse than simply leaving it alone.

 

Repair shop rates:

$10/hr we repair it
$15/hr you repair it
$20/hr we repair it, you watch

 

The original cap cans in the SVT from that era are the weakest part of the amp. If they are original from 1972, they should be checked out.

If the caps do need to be replaced: If you want to use the original FP type cap cans, Antique Electronic Supply (CE Manufacturing) sells them. Everything is on sale there now. They bought the original Mallory tooling and produce the caps. There’s an electrolytic cap in the top (preamp) chassis, don’t overlook that one. I like the F&T axial cap in that position that AES sells.

Personally, I prefer not to use these cap cans. Most people like to keep the original look and use them. Modern capacitors are way better. Retrofitting a modern cap can be a problem and that requires either drilling holes in the chassis for mounting clamps or designing a custom circuit board.

 

That's cool! I did not know that!

 

Nor did I yet there is this tickle of familiarity that tells me I once did know. I hate my poor memory!!
