If not we're back the the osc coil again. #7, the 600 Khz trimmer does vary the location of the signal as I vary the dial, not as much as I think it should, but it does vary the signal. I did check the coil for continuity as well as the oscillator voltages with a VTVM and all seem to be within tolerance.
