Trim pots for Technics SL-1500

Hey folks, I picked up a Technics SL-1500 pretty cheap last year, and it was great for a bit, then started acting up. The issue seems to be the 33/45rpm trim pots being worn out, causing the record speed to drift. I've opened it and used both 99% IPA and DeOxIt to clean & restore them. It works fine for a while after, but within a few weeks the speed will be drifting all over the place again. So I think I need new pots.

Does anyone have a source for new pots for these? The service manual lists the p/n as EVB0AK15B62, but this is either an OEM p/n or long discontinued, I don't see any references to it outside the service manual.

I've seen them on eBay, but they're all from turntables getting parted out. I'd rather buy a new part rather than a vintage pull, if possible, since there's no way to know if the pull has the same problem or not, or how long it'll last before failing.

Does anyone know a place I can buy these?
