Hi.
In fact I tried a 1N5819 in the set with not a sausage of output!!!
I have now reverted back to the diode between the G1's and ground, prior to that I tried the leaky grid again. It is really fussy as regard to grid leak value. No results with 1meg, open circuit it does work but very weak, 15meg gives an improvement and it works at its best at 10meg, with lower values it gradually fades to nothing at 3.3meg. Even at its best it is no where as good as with the ge diode. With the diode connected anode to grid the HT current on the AF amp drops with a strong signal, just what I expected it to do.
