Ron,
Not an answer yet on the oscillation matter, but I do have a question about the filter can, terminal #1. When I got into the radio, I found that at some time in the past the wire had been removed as I presume that section of the filter can had failed. I can tell you that the chassis was rather hacked, looks like yours fared better even with the mice. When I rebuilt the can (I was not lucky enough to have an already empty can around ) I routed a wire under the wiring harness back to the filter choke (Part #21) as per the schematic, no issue, but I do not believe that was where that was originally attached. I saw the photos but cannot make out the connections exactly...
Just curious. If you have a chance let me know.
As to oscillations, in looking at the schematic, I would think the bypass caps would take care of that. That is a puzzle. Maybe some else has the answer, but if I come up with a possibility I will let you know.
