Thanks for that input. I do have a dual trace oscilloscope and two probes, so checking the phase should be easy to do. Also if I ground the feedback and it eliminates the oscillation, then I could conclude the feedback is the wrong phase and reverse the connections at the transformer secondary and try again. It goes to show that using OEM parts simplifies repairs in many ways. The photo above shows many paper capacitors still there. Most have now been replaced except for a few that I need to order.
