Thanks Phlog and to you Brenda. And yes, the discriminator circuit looks much like those of FM receivers. Pholg when you say that no tone is necessary, should I just turn it off on the sig gen tone? If so, if I have a VOM on the speaker, well, don't know what will come out but willing to try. Brenda, your a bright light here and appreciate your help and knowledge. I'm wallowing in a lack of knowledge on this circuit. I have not figured out where item 97 on the schematic is on the radio. Seems it may have a part to do with the mag tuning.

Edit: Phlog as far as I can see the mag switch consists of a single switch (small rotary) combined to another switch on the back to change the "flood lights" on when the switch is turned to mag tuning. I replaced the switch as the old one had a broken up switch for the lights on the back of it. New switch seems to work well for both the rotary part and the lights.
