[Collins] 30S-1 relay problem

[Glen Zook]

According to the KWS-1 manual (section "section VI
Parts List") both capacitors that you mention are NOT
disc ceramic but are mica.  Those mica capacitors used
in the Collins equipment of that era are prone to
failure!

I've discounted the capacitors, since they should be
disc ceramics and the voltage is low. But then there
might be some inductive kick. And that might be
getting to whatever is running that circuit. At least
I am presuming that the two .01 caps, C135 and C212
(in my Yellow book schematic) are disk ceramics and
not black beauties.
