>>Did I create a ground loop and maybe should go back to a two prong plug?
Yes on both accounts.

As it turns out, no on both accounts.

How have you come to that conclusion? Where is the loop? Please elaborate.

Adding a ground plug to equipment that doesn’t have it originally is never a good idea. People do it, but people do lots of things.

I’ve restored 19 of these late 50’s RCA’s (very full basement) and have truly enjoyed the challenges, but this is the only one I’ve installed a three prong plug on…..not sure why either. Of the 19, only this one has given me this kind of issue. I won’t be installing 3 prong anymore for sure. As it turned out, the new cartridge was bad. All good now!

Maybe it doesn't know the words.

Not gonna lie, I’ve installed IEC 13 (standard) grounded sockets in a few older pieces of gear where it was just easier and nicer looking to do so. I just leave the ground floating in such cases to avoid any problems. I’d have used IEC 10 (ungrounded) but those are really difficult to source and the cables are hard to come by too. Also, polarity check before it all goes together just to make certain it’s all good.

Such is life, glad you got your problem sorted out easily.
