The strobe is a must. You can then figure out how slow you are. With the SDS you should be able to bring it up to the correct speed. However, if a strobe says you're way way off, then it's best to find the reason for being so slow. Since you've got the dual motor flywheel, make sure the flywheel is lubricated. Make sure both motors are spinning (take the belts off to verify this). Make sure both pullies are tight. Make sure the motor is not too close to the table. Too close and you'll have no belt tension. I think mine is about 1/4 inch away (i have the rim drive, however). Finally, make sure nothing is coming into contact with the platter and slowing it down with friction.
If speed checks out, then you might need to check your cartridge, tonearm wire and phono pre-amp. Is there any possibility that your cartridge got damaged? Cartridge pins on tight? Is the lemo connector inserted correctly and seated?
Boy, I'm tired. Maybe CD IS the way go?
By the way, I just listened to the new "Astral Weeks" reissue. Spectacular! (Although it's the first vinyl edition I've ever owned. My only comparison is to the really incredibly shitty sounding CD that I bought in the 1980's.)
Cheers.
