Anyone in the US that can repair turntables

Most qualified service centers would require a schematic of the table's electronics in order to be able to tackle such a repair, especially since you say how complex the servo feedback system is.

Yeah I thought about that already. I might ask him if he’s willing to provide it.

What's the brand and model #?

A Service Manual might help. Check HIfi Engine. They have a huge library of manuals.

There's probably an adjustment that sets the servo. Perhaps this adjustment is a bit out of whack. But of course, read the Service Manual first.

IMHO, one of the best techs in the country.
