Question for VPI Rim Drive Owners

I recently acquired a VPI Dual Motor Rim Drive at a great price from a friend and got the Super Scoutmaster Chassis from VPI. I have now converted my Scoutmaster to a Super Scoutmaster.

The Rim Drive does have the rubber footers and the latest belts. So far, I have noticed no rocking of the tonearm that seemed to have plagued some users. I may at some point try the Bearclaws that people have been raving about.

I have the SDS and have dialed in the right speed with the KAB strobe. One odd thing that keeps happening is that when I check the speed each day, it seems to vary slightly so I have to slightly adjust the SDS. Has anyone else experienced this? Does the Rim Drive need to run in or warm up?

Any input would be appreciated.

Thanks

I have removed the Gingko from the system as the SSM was too big for it. I have the SSM set up on 3" thick maple platform with threaded cones under platform.

I am still having some issues with speed fluctuations. I listened to the system for about 6 hours today checking the speed every couple of hours with the KAB strobe disc. For most of the day it stayed rock solid. I checked it again late in the day and the platter speed had slightly increased. So I dialed down the SDS a little bit more. The SDS is set at 59.50 for 33RPM and 80.5 for 45 RPM.

I am wondering if I should reset the default voltage on my SDS? It's set at 84 for 33RPM and 114 for 45RPM.
