[Hammarlund] SP-600 BFO waveform

[stbradford]

Hello list,

I have observed a very distorted wave form from the bfo oscillator. With
the buffer removed and the scope looking a the input from the g1 pin.
It's also the same wave form at the physical output of the 6C4 bfo
oscillator.

All volts and resistances are reasonable so I have removed the bfo sub
assembly from the receiver. The various silver micas are on the way,
they were all available from Mouser. The schematic has the same values
that I found in the sub assembly. I will check the caps on the capacitor
bridge and see what it shows. But considering the difficulty in removing
the assembly I am going to replace all 5 of the caps.
