Turnable database with TimeLine


Here is a database showing various turntables being tested for speed accuracy and speed consistency using the Sutherland TimeLine strobe device. Members are invited to add their own videos showing their turntables.

I did lose something it turns out. After dark when the ambient noise level was at its lowest, I could hear some rumble. It is faint; but there. So the bushings are transmitting some mechanical vibration from the chasis to the sub chassis. I have some ideas to try out. I can't go back to an unconstrained horizontal axis...
I overreacted. The last record that I played the other night must have had noisy vinyl. I listened last night and heard no rumble. I cranked up "For Duke" again. This record has dead quiet vinyl. Sounded great- saxophones and trumpets all over the room.
I think that back in the day, a few tweakers used to disable the suspension on SOTA tt's entirely and then mount them on any of many various isolation platforms. In other words, turn a suspended tt into an unsuspended one. Let the platform do the work.
Rather than hijack this thread some more (sorry Peter:-) I have done a write up on my turntable mod at my system page.
VICTOR TT-81
This turntable displays the same (if not better) accuracy as the TT-101.....
I believe the difference in the speed accuracy and consistency WITHOUT load compared to that WITH load is of some importance....and that's why I like to see the Timeline mark playing the record compared to NOT playing.....
The reason I believe it's important is that the musical waveform on the vinyl record can be quite benign on soft unmodulated passages (not to mention pauses in the musical content)...whilst with loud, heavily modulated passages...the stylus drag can be quite severe?
If there is a marked difference in a turntable's performance between playing a record and not playing.....there must be a gradient in the speed accuracy when faced with benign passages as opposed to modulated ones?

At any rate.....despite what opponents of DD turntables like to say about their sound and 'speed correction seeking'......there is no physical evidence of it with the Timeline which is rock solid.
