VPI SDS help

I had this exact problem with my Rega 25 and VPI SDS. I found that if I gently help the turntable platter gain speed (on startup) by gently turning the platter by hand--giving it a gentle shove--the SDS will drive the Rega 25. I guess the SDS doesn't have the power to overcome the inertia of the platter at startup; but once the platter is spinning, the SDS drives it without further problem. Without doing this procedure my Rega would sometimes play at a speed below 33.

Mees,

thanks for the suggestion. Once the SDS began to drive it, did you find that SDS maintained accurate speed for the TT at both 33 and 45rpm?

My SDS will work with my Basis 2001 at 33 but the table will not rotate at all when I switch to 45. I get the correct speed by switching the belt. Speed is accurate at both 33 and 45.

Mike,

Regarding your question, once I help the SDS get my platter spinning it maintains its speed perfectly at 33 rpm. I don't use 45 rpm. I will add that I have been very happy with the improvement in sound that I get with my SDS.

I had the same problem using the SDS with my Rockport Capella II. I borrowed a 230V output SDS (as I was in Hong Kong) to power the Capella, and while it worked fine for 33, the platter would slow down and stop when I switched to 45 with the SDS. The same thing happened to the PS Audio Powerplant 300. I wrote to Walker asking whether their controller could drive the Capella, and their reply was negative, stating the Capella’s motor was too big. Apparently there are turntables which the SDS is not compatible with!
