Hi MrFixr55,
Thank you for clearing up my confusion about the AVC line and the volume control tap. I knew there was an RC network that filtered the AVC signal. I did replace both the filter capacitor and resistor in the AVC line so I think that part is okay. But something is not working properly as the AVC doesn't seem to be working as it should. I did go over the band switch to make sure it was clean. But now that I did that, I noted that this switch has been worked on as some of the solder joints looked new. Since I did find one wire from the oscillator coil just hanging loose, I'm wondering if everything else was reconnected properly. So I will be going over that switch carefully, especially the A wafer which controls the oscillator coil.
Thanks again for your help and insights!!
