Fred,
Do you have a scope?
If so, start looking stage by stage to see where the issue is...then
fix that stage.
Since you don't have any Spot...it is before the finals for sure.

Well, the problem continues.
It worked for a short time but is not working again. Replaced V-1 and
V2 with tested used tubes. V1 was N.O.S.
I did substitution of all the tubes with used and tested tubes without
any change in output.
The spot position does not put out a signal either. Even when put into
AM and using the spot function, I can hardly hear that tone in the
receiver either....
Both VFO's will work the receiver.
I have idle current when in tune position or when PTT on mic. no other
output. No output when speaking or whistling into the mic either
Any other ideas?
Where to look next?
Sprayed the wafer switches with Deoxit and another plastic safe contact
cleaner even though the wafers are phenolic and not plastic. Band
switch is not any stiffer than it was when I bought the twins 5 years
ago so I don't think that is the problem.
I tried 75 meters and 40 meter both with the same results. No
output.....
Where should I start to look for the problem? Any ideas would be
appreciated.
Thanks
