Music Hall mmf-7 spins faster

I have a Music Hall mmf-7 turntable (EAR 834P phono preamp) and it spins faster than normal. I bought a new motor and a new belt from Roy Hall, but it didn't change a thing. I borrowed my friends' motor (he has an mmf-7.1): no change... I even bought a Pro-Ject Speed Box (on Roy Hall's advice): it still spins faster. My cartridge is a Sumiko Blackbird. I really don't know what much else to do: any ideas? Did someone run into this problem?

I am desperate.

Nope, not at all; he was very happy with his mmf-7.1: just the upgrade bug. I simply asked at the perfect time.

You seem not really happy with Music Hall turntables: may I know why?

I like my MMF-7 -no problems whatsoever.

Lrmellon: Now you can swap all the parts from the new MMF-7.1 and see what happens.

I think the ".1" is a change to the tonearm.
The rest should be the same.

Good luck!

I am going to swap the motor, the belt, the sub-platter and the platter and see what happens.

I swapped the motor and, surprise, surprise: it is now much slower, almost not turning at all. I am going to change the platter and the sub-platter now.

Did I say weird?
