Question about Remote Controls
I have an old Zenith Trans Oceanic L-600 that is in very nice condition, however it recently started to develop a lot of static and a noticeable decrease in the volume after it warms up.
Does anyone know if this is a common problem and a possible solution?
I am not sure, but it sure sounds like the filter capacitors on the input from the power supply are shot. What may be happening is as the radio heats up the caps are breaking down and allowing unfiltered dc into the circuit. It can cause the kind of noise you are talking about. If that is your problem it is the ac going back and forth (alternating between positive and negative current 60 times or cycles per second) By the way cycles per second (cps) is now called hertz. (hz.). Recaping or having all the paper and electrolytic capacitors replaced in your radio may solve the problem. Consult a quality radio service center.
