Hello.
Was just given an old all-in-one home stereo. Zenith Digilite, the one with knobs not sliders. It's one of those all in one units that had a turntable on top, 8 track player built in, AM/FM/FM stereo, AFC toggle. I am guessing its manufacture between 1970-1975, forgot to check date on it.
Here's the only problem. Only on FM, it hums (well, admittedly I didn't test AM thoroughly). It does not hum on tape mode. It has inputs on the back, I connected a modern MP3 player and it sounded great. I have tried connecting an external antenna to the FM ant screws and that helped pull in more stations but made no difference in the hum, so I don't think its antenna related. And it doesn't seem power supply related, if tape and input modes don't hum, correct?
Your help is really appreciated - for how old it is and how small the speakers are, this thing sounds great!
