I've been restoring a WRL Globe Champion 350. So far all has gone
well, save this mystery: I have lots of drive on all bands except 15
m, where I have almost nothing. I removed the VFO and cleaned the
contacts on the switches, but saw no change. Lots of drive on 160-20
and lots of drive on 10, but almost nothing on 15.
As a test, I inserted a 40 m crystal for 7150 kHz and that tripled
just fine, producing plenty of drive, and an output frequency of
21.45 MHz, just as it should. So the 6CL6 buffer amp is fine. What
else should I look for? I suspect a bad capacitor, but I can't find
any that are unique to 15 m.
I'll happily entertain hints and suggestions.
