VPI Traveler


The Traveler, and the Classic 1 now have an additional circuit board in them that does essentially what the SDS does...it creates a much better power source for the motor. There are no adjustments, but the tables have improved performance. Harry is always making his stuff better.

String .. , you're pretty close with the VPI folks. Do you think I can re-configure my Classic TT to incorporate the new mod? I might even exchange the motor for the 300 rpm motor used in the Classic 3. You may recall that I already upgraded the complete tone arm/wand assembly to the Classic 3.
Bif...I would suspect that the upgraded tone arm didn't bring you THAT MUCH improvement. The addition of the mod on your Classic would be about the same. If you want a serious improvement, think about getting Bearpaws for your table.
My dealer tells me that both the Classic and Traveler have a built in circuit that is similar to the standalone SDS but without about ability to vary the frequency nor does it step down the power once the table is up to speed.
String ... and Brf -- I spoke with Jack at VPI yesterday about the new changes made in the Classic TT. Most are gingerbread (e.g., button on top rather than side).

As to the new circuit board, Jack said it's really more of a manufacturing convenience point. Jack said that the Classic motor is AC synchronous, which means it maintains constant speed as long at the wall socket frequency maintains 60 Hz/second. Voltage swings are not as critical.

Jack explained that the manufacturing convenience point is that the motor will maintain proper speed in other countries where cycles per second may be 50 Hz, or not be constant at all.

I asked Jack if it's work the tweak to install the board. He told me to save my money and put it into vinyl or Bearpaw Feet.
If the motor can maintain speed at either a 50 or 60hz without a change in pulley, the circuit must be doing some form of power regeneration to a 60hz frequency.
