Default Speed sensors...

EB, that looks like almost any other optical sensor out there, as used on many turntables for example: the Dual CS5000 uses something similar to control the auto functions, the sensor is mounted to the tonearm base circuit board, and a piece of thick mylar is used to block the signal allowing the motor control energize the motor. There are others that are used for a speed feedback to a motor or motor controller. I see no reason why it couldn't work. You may be able to get a similar sensor that is a direct laser/light and receiver that point away from the sensor itself---a "point and shoot" device that would allow you to shoot the laser/light onto a surface and receive the reflected light. I guess this is a laser tachometer...

I must say that I am not an electronics engineer, and thus maybe I'm dreaming...but I can't believe that this is not "do-able". I will say that if you are planning to use a control such as this on the ROK turntable, you would be better of using a good motor and typical shifting capacitor. It will be much easier to actually do and maintains the basis that is the ROK. BTW: I'd love to get my hands on one of these great old turntables.

THe VDS system is something that I would like to experience myself. If the rubber seal is deteriorated, can a new one be purchased or made? I think Luxman turntables have been forgotten.
