Either motor is dying (losing power) or like you say there’s friction somewhere that the motor only intermittently overcomes. But if records sound normal in terms of tempo, then I would either doubt friction hypothesis or look for an intermittent cause. Take the whole thing apart. Clean and relubricate the bearing. Check that platter spins freely. Make sure belt fits snugly around pulley and platter. Etc.
Pro-Ject Debut Carbon Turntable working on and off
My Pro-ject TT is working again, but 3 times this year it has shut down and won't spin.
After the 1st time, I took off the band and put it back on, and not much else except for that. It worked fine for a while.
2nd time - I got a new band. Started working again.
3rd time, removed the inner platter and re-placed it, and the put the band back on. It's working again.
It's not a connection issue as far as I can tell.
It's fine now, but I can't feel confident it will stay this way.
It's about 9 or 10 years old. Great when it plays...
I've gotten lazy about picking up the tonearm when an LP ends, and have let it stay on the run-out for a while a bunch of times. I've since stopped doing that, but I wonder if that had an effect.
What do you consider the problem and potential solution might be?
Thank you.
