Outboard speed control for Thorens TD-124

I don't think the Music Hall will work with 124 because it needs more torque than the 160. The Music Hall and the Pro-Ject are the same thing.

Phoenix Engineering...mmmmmm,I'll hit them up.

Checked out the Phoenix. It won't work because there is not enough clearance from the platter.

Need something like the Wave Mechanic.

"Every speed control I have ever seen, is an external box that you plug the motor into"

The Phoenix is different because it uses a small magnet that you put underneath the platter and then a small pcb card between the platter and the plinth so it can read the magnet, kind of like a strobescope.

The VPI might work, as long as it sends out AC, correct?

I am surprised that no one has come up with something like this for idlers. I mean, they make every audio gimmick in the book now, and this no gimmick but a real need; weird.

So, I did some more research on various forums and got some good information.

First, the Nott wave mechanic or VPI SDS will not work because they are for 7 watts and the 124 needs 15. Second, some people have indicated the stepping down the voltage to around 117 volts is advisable because the 124 was made for that voltage not the 123-5 that we know are given. Also, that to regulate the voltage is a good idea because of the voltage swings through the wall (that is really not the case for me as it only drifts 1 or 2 volts at the most). Last, and most understandable is trying to get the best possible sine wave you can feeding the motor as it is asynchronous.

Does these points sound reasonable?
