I thought I'd sent this yesterday, but turns out I only replied to Bruce:
The culprit turned out to be a bad ceramic bypass cap downstream from
the VR tube. The cap doesn't even show on the schematic in TM 11-806-
must be a later revision.
I guess it shouldn't, but it always amazes me how a 10 cent part can
be the difference between Go and NO.
Thank you, thank you to everyone who responded with suggestions. I
now have a full 110 watts out of the transmitter. Modulation is a
bit weak with the M-29. I have yet to determine whether it's just
the microphone or a transmitter problem, but the days not over yet.
Thanks again,
Robert
