vpi classic works with music hall cruise control

IMO, the primary function of the VPI SDS is not necessarily a speed controller but more a voltage regulator. It uses full voltage on start-up then reduces voltage when the table is up to speed. This results in a reduction in the pulse of the synchronous motor. Speed control is also available on the SDS.

The Cruise Control (TTBOMK) is only a speed controller.

Another less costly option to the VPI SDS is the Heed Orbit II. I haven't tried it, but the concept seems the same as the SDS.

I wouldn't do it, but that's me. Also, because VPI knows their products and I trust their knowledge. But at the worst, you'll take out the motor and Music Hall unit. The VPI motor is about $150.00 plus any capacitors/resistors (I forgot what the circuit looked like) that you make take out sooo, on the VPI side of things it might cost you $200.00, if it goes south. If you're happy with it, run it till it drops.
