Oscillation may be triggered by clipping of the audio signal, in some situations. This means that an amplifier can have no apparent oscillation problem at low output level, but may oscillate if the amp is driven hard into clipping, with the same input signal. A triangular waveform signal is useful for this observation.

I think this may well be due to the op-amp driving the first transformer. Previously I mentioned that the Q1 would look like about 100 ohms of load to L5 (325 mH) and if this load impedance is referred to the primary it will overload the op-amp and easily produce the extra 17 degrees to cause oscillation.

Basically, our OP has created a square wave oscillator (but not really, as opamps make for very bad square waves).
