The output waveform from my Taylor 65B is not what I would expect.
Instead of a symmetrical amplitude modulated wave, only the bottom half of the wave is modulated. The top half is flat.
The 400Hz from V2 is clean.

I have replaced the usual caps and a few out of tolerance resistors but the output is still dodgy. Can anybody shine a light on why the output would be asymmetric?

Thanks.
