The problem turned out to be a 220 mfd 10 volt cap on a 8 volt rail. All
better, working fine.

I recently purchased a very nice condition 471A radio. Knowing it had a
problem and looking for a winter project. The problem is no USB or LSB. CW and
FM work fine. I have traced the issue to lack of voltage at the SSB oscillator
circuit. Has anyone had this issue with a 271 or 471 radio ? Thanks Mike
