Lawrence.

Nor I.

I Think, (you said), the FM discriminator is the DC return, but the set works on MW without the diodes there, provided R6 (2M) is in place. I've tried the set with the discriminator working and connected, but without R6 and it doesn't work very well (low distorted audio).

Why? Or what that is telling me I just dont know.

Thanks,
Amie.
