I’d see if you can find a circuit diagram for the equipment, then compare it against what you actually have.
It might be that there was a genuine issue with the equipment that was fixed, or it might be that the fix was actually something else entirely.
There’s no way for us to know what you’re dealing with.

I have the manuals and I can check those. I can also easily get the model numbers off the units. Are diagrams something that you can find for old hardware online?
And I appreciate the assistance. My background is in computer science, so my electrical engineering abilities are slim.

Fellow computer geek here … also a radio amateur.
No idea what the availability of circuit diagrams is for your gear. In amateur radio equipment the user manual regularly has them, sometimes as big foldout sheets. I’d be surprised if they didn’t exist.

Thanks for the information. The two units are by Fisher an FM-2421 and CC-3000.
I’m not seeing full circuit diagrams, but they do have some information on what to wire up.

Antenna ground needs to be used for signal to be read properly.
Turntable audio grounding (different from electrical power grounding) may help prevent hums when the common 0V grounding passes by the power ground.
