Re: {Collins} Tough problem in 32S-3 (still)

Well, I also thought it was a bad C-62, but there are a couple of problems with that idea (I think anyway).

The problem with the C62 theory is it is connected directly to the grid drive line to the finals.    If it went high in value enough to kill the AGC, it would also kill the grid drive, yet grid drive is fine, the same as my other 32S.

The practical problem is that cap would be a real bear of a pain to replace or even just disconnect.  It is very hard to get to, inside one of the band switch cans, plus it has 8 connections on one side, some from the fine wire on the coil forms, and a coax connection on the top that is very hard to get to.  Have to remove the slug rack.

Even if I knew it was C62, I don’t think I would attempt to replace it unless I could come up with a strategy to replace it without damaging other parts. 

If I think of something, I’ll let you know.

> Hi Grayson, sounds as if your problem may be C-62, the feed trough cap. Is there a way to disconnect both ends and use anther regular cap to provide the voltage wit out messing up the neutralization or grid drive. I don't currently have an S-3 or I would take a closer look for you.
