Could there be some leakage from the phono motor coil to the chassis?


Well, Bill it did turn out to be related to the motor. When I 'scoped the audio output with the motor on I had these large spikes in the waveform at a 60cycle rate, turn off the motor and they went away. Ended up installing .05uf cap from the motor AC to chassis ground - nice and quite now.
