[Johnson] Aux. coupling capacitor replacements

[kwylow zinjanthropus]

The smaller button transmitting capacitors are possibly the best types of replacement for your application. In fact, I had a Valiant with such a bank of caps that was installed.  Odd about the Sangamos. I never knew they would do that although some of the older "postage stamp" micas have been known to short over as a result of silver migration. Cal, N6KYR

My Valiant I and Thunderbolt both have shorted aux coupling capacitors. 
If you've dealt with this situation before, what did capacitors you use
to replace them & whre did you get them?

Note: I've accumulated quite a pile of Sangamo type "H" cast mica
capacitors for use as possible replacements. When tested, each and
every one of them was shorted, whether they were new old stock or used. 
Beware! Other brands (Sprague, Aerovox, Solar) were fine, but the
Sangamos are JUNK!
