I think my issue is actually ground loop hum. Can it be the some radios are more sensitive than others? Strange the older Philco 80 was not effected. I turned on my old Aircastle today and there was an annoying interference hum and buzz. Turns out it was a small electric space heater in the basement. Every time it kicked on this would happen. Also I have "can" ceiling lights on a dimmer that cause this problem too. Is there a circuit design for a strip terminal type that I can make to plug all my finished radios in, to enjoy in the living room? Humm eliminators are $70 a pop. There cant be much to them to make your own.
