VPI Traveler

Is the circuit board an AC regenerator that also reduces the motor voltage after startup like the SDS?

I doubt that!

BS from VPI!

String.... I wonder if existing Classic tables can be upgraded to take the new circuit configuration?

I understand that the Traveler, andClassic series is now being configured with a built in SDS-like gizmo so there's no need for an SDS.

Talk to VPI ....anything is doable.

The SDS regenerates the AC to eliminate line noise. Then the resulting output voltage has a crystal calibrated oscillator with the frequency, that you set. to keep the the motor speed exact, compared to the supplied strobe. The SDS also generates a flattened sine wave that is reduced in amplitude, for reduced noise, after the motor starts.

Do you think a simple circuit board can do all that?

Harry is feeding you B.S.

That little circuit board is no SDS!
