I sold a Drake C Line to a ham friend a few years back. It had been fully
functional for me for months and the fellow came over to pick them up. I fired
them both up in front of him, on my antenna and went everywhere, all bands,
everything worked - HAD FUN!
He carried them out to his truck (smi
I have used de-oxit many times on old National, and Clegg equipment,
both on switches and on pots. So far, I have had no trouble from it. I
may even have saturated the wafers on a switch or two in the process to
no ill effects. I am much more careful with it now, though. Many of
these com
Hard to imagine DeOxit causing the problem as you used it sparingly (vs
flooding the wafer and possible inducing swelling). Did you exercise the
rig immediately after applying the DeOxit? It is somewhat conductive until
dry.

Garey,
I agree that Tom's capacitor kits are excellent, but they really don't come
with "instructions" as such, even though the cans "symbols" on the bottom
even match the originals. You won't say it, but I will, that the guys need
your fine CD's to find some of the little hummers on the board

Nah, I don't think you can blame it on DeoxIT. Got the FUNCTION switch
in the ON position?

I wanted to clear up what we were talking about.
If the issue is on receive, then you need new filter caps in the
receiver. The receiver has it's own power supply, completely separate
from the AC-4 transmitter supply.
Assuming all the caps in the AC-4 have been replaced, there is no
I've had vibration experiences with several Drake power supplies and have found
