Hello kind members,
I got a good deal on an original 4002 turntable that is having speed issues. Tone arm and electronics work, the record spins, and it is producing sound. However there is an incredible amount of wowing speed fluctuation. What parts should I be looking at and could someone guide me on a process of elimination for getting the turntable running smoothly again? Alternately if anyone knows a good tech in the PNW, i’d be glad to know them.
Thank you 🙂

Listen without amp but record on if there is some scraping noise from platter to other parts inside.
Beoparts (now: Danish Sound Parts) provides the right platterbelts
If you are already working on the turntable maybe you renew the belt for the tangential drive too.
Kind regards
Christian
