my osc is just a single hrz, I may have anoher will have to check around
BUT
I did disconnect the singe resistor that connect both the transistors bases, other than the bias voltage being a bit further off than before (it tied them together) I could hear no difference AND much better separation.
about 10 to 1 where it was about 3 to 1. clearly that resistor was the signal path between the two channels, whats left is prob un decoupled from the B+.
I am going to listen the to radio all day tomorrow and see how it does.
I may go thru my stash of transistors and see if I can match some (I have a transistor beta checker). Just to see how close I can get the bias.
