40-140 Audio detector question
#8

I definitely screwed up my drawing  but the Philco drawing shows a resistor #34 between the two diodes. In my drawing I have the resistor in question as #33e 47k which is wrong it should have been #34 at 2.2meg.

We must be looking at different drawings. The one I am looking at is from the link above.

Which capacitor do you speak of?  What's the circuit number?

!!!!!!!!!!!!!!!!!!!RESISTANCE IS FUTILE!!!!!!!!!!!!!!!!!!!!!!
