I've got the receiver sitting upside-down with the bottom cover off, waiting
for it to start its dance. I happened to probe around, and both at the wire at
the output and the piece of buss wire going to the bandswitch (and the
crystals) I can pull the frequency.
The supply voltage is around 11V. When the receiver starts warbling and
jumping around, I can see the waveform at the output slightly jumping.
Now - something else that's interesting: There's about 0.1V p-p of RF ripple on
the 11V supply. I tried bypassing it with caps on hand but couldn't make the
ripple go away.
I'll be digging into the 11V supply that's fed off the +160. The 11v is
derived from the 0B2 gas regulator. I had previously swapped tubes and it
didn't have an effect.
More as I find it...
