Hi.
An update on some further tests.
Adding in a diode between D1 anode and ground virtually damps the audio to nothing as does a good low capacitance 2.5Mh choke. Seems the only way this performs is a Diode with no DC path or with very high resistance values where there is a marginal performance gain, distortion is also less. I also found two AA143 diodes that work well except for more distortion. I'll now wait till I have the 1N60P diodes I ordered.
