Finally, some closure: I have both turntables (mmf-7 and mmf-7.1) spinning correctly now. After a lot of tweaking, I finally put a little (toilet) paper on the small rod on top of the motor before easing the pulley, giving it a snug fit. Since then, no more speed problems. It even works perfectly with the Pro-Ject Speed Box II now. In fact, there was no adjustment screw (and no place to insert one) at the base of the motor pulley, thus making it going either too fast (or too slow): "élémentaire, mon cher Watson!" as the French would say...
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.
