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

Call or email VPI and see if they have had experience with this combination. I am currently using an SDS on a non VPI table; a look at members systems will show that some others are also. But each table has its own characteristics.
I emailed VPI based on that good suggestion here.

VPI responded:

Check the capacitor on your motor, if it is less than .68 microfarads you need to change it for a .68.  Less than that value and the SDS looks at it like it is a short.

MY Question now is how easy is it to change capacitors on a turntable motor?

Thanks

You may need patience trying to reach VPI - they often don't answer the phones or respond to e-mail for days at a time. There is no excuse given the size of their customer and dealer base.
