Hi all, I've been loving this table since rebuilding it but it's not great at holding speed. It shows .2% wow on a new phone app I tried and seems to wobble on the strobe and is hard to get the speed to lock in without drift.
I've replaced the electrolytics and disassembled the motor, cleaned and re-oiled with synthetic lube, and replaced worn plastic thrust pads under the spindle with PTFE.
I should note that it runs perfectly true, smooth and silent.
Looking at the schematic there are trimmers R54 "Duty Adj" and VR1 "switching balance adj" at the bottom but no mention of what they do in the service manual. Can anyone recommend some things to try here? I was considering replacing the speed control pots and trimmers.
Thanks. 🙂
