Hello, I'm a new guy here and have a question with my Philco farm radio Model 42-122.
I get a hum maybe buzz On Station Only. Now to explain : I do not have that problem when I run it on batteries.
I have the problem when I use the 90vdc - 1.5vdc power supply I made. I followed a well used version of the power supply - battery eliminator. I've checked everything for proper hook up. It seems as if it is the power supply at fault, I would get the hum all across the band, station or not. I do get the station fairly clear but with the noise riding it,, only on a received station. Thank you for any help, tips.
