Re: {Collins} 32S-3


Waxy surfaces, and wax bubbles on the ceramic caps of this age are quite normal. Look for discoloration or, better yet, check for faults in the caps with a good high impedance VTVM. If you find very peculiar "bubbles" or discoloration tied to the circuitry associated with the blown electrolytics you mentioned, then take a very close look at those.

Hi, All:

I'm in the process of bringing my 32S-3 back to life. I noticed that many of the ceramic disc bypass caps (.01, .1, and .2) have what appears to be
wax bubbled out of them.

1.	Am I correct in assuming that these have been cooked somehow and
need to be replaced.
2. Aside from a blown electrolytic and an obvious short in a lead to RY
1, are there any other causes I should look for?

Thanks in advance for sharing your experience and sage wisdom.
