I had posted in analogue, but I think the cool cats of the DIY lounge may actually provide some in sight.
These devices seem to be very brand centric, they may not work with another tt from another company. Is there such a thing as a generic speed controller? Is it possible to build (or get a person that can) your own?

The Music Hall Cruise Control 2 can be used with any turntable with a 120 volt A/C motor, that does not draw more than 3 watts, unless that turntable has a regenerative power supply built in.

Cheers,
Alec

Hi Alec.
I have a Rega Planar 3. Will the Music Hall work with that?
It is 120v ac and the original suspended motor.

Do you have a specific table in mind?

Motor controllers are matched to the type of motor i.e. DC or AC synchronous and the motor's power requirements.

I'm using mine with a Rega Planar 2 (1982), GrooveTracer subplatter, Sumiko/Jelco Premier MMT arm.

Cheers,
Alec

Hey Vpi SDS is the best speed controller I've found for use with AC motors. The music Hall is not big enough for some of the motors but you are fine with the Vpi with all motors

It is a VPI, I just can't get past the price.

I checked out the music hall, it's definately affordable.
I haven't actually seen one, but it looks as though the the unit only takes a two prong plug. The power cord off the motor on my VPI has a ground pin.

Traveller?

The VPI is a good deck. Why do you feel you need a speed controller?

It's the scout II, and I do love it.
I did some readings with the rpm app and also used a strobe mat. It would seem it's not running to speed and it may be inconsistent speed wise as well.
So it falls into the compulsion/reaction category. Now that I know somethings not quite right, I would like to have the tt running at perfect speed.

The Scout 2 has a stepped pulley, therefore, moving the drive belt to a different pulley groove allows for fine speed adjustments. Try playing with belt tension to allow a more linear transfer of power which will result in better speed consistency.
