Well, now that I own a fully working oscillator.....this evening a ghost was howling in my house.
Long story short, I hooked it to the pre-amp 27 tube and watche excellent undistorted output on all frequencies up to 7-8V peak at the speaker voice coil using the scope. This makes it at least 5V RMS which makes it at least 4 Watt output on the speaker.
Quite good.
So the residual distortion I am having when the buzz no longer an issue comes from RF, I think from the detector.
Well, the audio amp and the speaker and transformer are exhonerated.
