Outboard speed control for Thorens TD-124

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

You may be talking about something else here. Every speed control I have ever seen, is an external box that you plug the motor into. Also, torque shouldn't be an issue. You'll still be giving the motor what ever amount of power it needs to run.

Would the old VPI PLC work with the TD-124 motor? There are a couple for sale on AudiogoN at the moment.

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.

Yes. If you don't already have any A/C products, you can use a regenerator like a PS Audio 500. 2 upgrades are better than 1.

You are referring to the Roadrunner from Phoenix. It can be paired with the Falcon, which controls the speed. But the Falcon can also be used as a standalone. I use it that way, and confirm speed with my trusty Kab strobe.
