RCA 8X71-Hum
#1

I've got a strange one. All electrolytic and wax caps replaced. Resistors replaced as necessary. Tubes tested. Set aligned on both AM and FM.
The problem is that I get a hum on AM only and only when on a station. In between stations on AM is silent as well as FM.
Any thoughts?

Thanks,
Eric
