Another option to consider: Feickert' PlatterSpeed app, which
can be downloaded to a cell phone or E-reader from
"platterspeed.com". It's easy to use, works very well, and is
very accurate. It will require having a test record with a
3150 Hz signal. Feickert has a small test disk -- called
"Adjust+" I think -- that you can buy to use with
the app, but it's inexpensive. Using this app and disk, I was
able to dial-in my turntable's speed to +/- 0.2 Hz of 3150.
(I have a VPI Classic 3 with SDS).
