Control Oscillator module repaired, bad solder joints on the E2 Discriminator board.  Actually these boards use a little thru hole hollow rivet for the component legs to solder to, then the back side of the board has the traces.....several rivets weren't soldered down to the traces.  Obvious upon visual inspection. So now RX OK!

Tried TX after installing the 2n5884 Q1 & Q2 replacement....chopper / oscillator won’t run and base resistors to transistors getting hot.....have to figure this out....might be the supply T1.

Any guidance here?

Thanks,
Steve
