VPI SDS help

I bought a VPI SDS here on Audiogon for my townshend rock 7 turntable. According to my research The rock 7 is ac motor 110 volt.

I installed the SDS with the TT but the TT motor is spinning very slowly at the 33rpm setting. I changed the default sds voltage from 72 to 115 but it's still slow and increasing the frequency from 60 to 65 did not get it working right either.

Am I doing something wrong or does the SDS not work with this TT

I had no luck with the "gentle shove" method with a 45rpm record. My turntable dealer is checking with the manufacturer if the capacitor can be readily changed on the motor to .68 as suggested by VPI

An old thread, but I wondered if Radioheadokplayer ever got this combo to work? Or anyone else try to pair an SDS with the Rock?

I use the SDS with my clear audio master solution. Heavy platter that needs a little help to get spinning compared running motor direct to ac line.

Once spinning it is very stable and also easily spins up to 45 when switching the SDS. I felt the improvement was noticeable.
