VPI Speed Problem


I have a VPI Super Scoutmaster with SDS. Fabulous sound, had it for about a year. I moved to a new place about 5 months ago and have had it set up and working well for about 3 months in the new location.

Recently, I thought the first song on some album sides sounded slow, but as the album played a minute or two, all sounded right again. Now, everything sounds slow all the time, both 33's and 45's. I tried bypassing the SDS, though there is no speed setting on the motor assembly, so I don't know if that should sound right, but it sounds very slow and muddy as well.

Any thoughts on what might be wrong or how to troubleshoot? Any insight would be appreciated.

Kthomas,
I recently purchased the remastered Moondance. Compared to the original, as in many pressings, I prefer the original. Many remasters sound overdone. In this case too bassy, vocalist in your face and music seems either bloated or in the background. With the original, the band and Van seem to be in the same room, playing with each other on the stage and not in separate rooms with their own volume controls (bass and vocal mic beefed up). That's how I hear the 2. (Could be the crappy Lenco.)
On another note:
I just saw a a film at the NW Film Festival called "Irish Rover" good footage of Van playing with Dylan and The Chieftians.
For his earlier stuff, which I like very much, get "Van Morrison In Review" on eBay for $18.00.

For general knowledge, the way I set speed is by ear, when the record is playing. I play the exact same title on cd, from that same master tape source. I do this with a few records/cd's and A/B back and forth during play. When the sound is perfectly in synch, I leave the SDS at that frequency. Do this after you set the VTF/VTA etc.
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.

It could be your phono stage or preamp also. Check this by letting your turntable run for a while then play the record if it still happen then it is else where in your system and not your TT. This happened to me in the past and found I had a problem in my phono stage.
