What happens if you look at the discriminator output? What if you switch to FM mono? Maybe there is a circuit right after that output that "preamplifies the demodulated signal before it gets to the common audio circuits? Lenny



No change in mono mode Len.

In any case, it doesn't matter. Customer doesn't use FM so he picked it up yesterday.
