Turnable database with TimeLine

Yes, early on I did receive some private emails suggesting that a few more people would try to upload videos, but this has not happened. I think the test can be quite revealing of one aspect of a turntable's performance, and it is a shame that not more people want to add videos.

I friend just bought an SP10 MK3 and perhaps he will let me film it. I have another buddy with a TW Raven.

The thread drifted into other subjects and became more than just a video database and this might have halted the momentum.

Further data for the list.
Way back on the "Turntable speed accuracy" thread, Dover posted results of stylus drag on his Final Audio TT.
From memory, this came out as 2mm movement per rev on a 400mm radius, when stylus lowered. Don't recall a video being posted, but this is still worthwhile info.

Thanks Richard. If this is using the thread drive and I presume a vey heavy platter, I'm surprised by the result.

Yep, I went back and had a look at the posts, 05-29-12. on "Turntable Speed Accuracy" thread

Heavy platter and thread drive.

"... do you perceive that the TT-101 and the TT-81 have exactly the same motor? It looks from photos that the TT-101 motor might be different in size or in some other way from that of the TT-81. I know they are both coreless types."

I have only owned the TT-71 before and I do know the it uses a core motor. Based on motor model numbers (TT-71 = M932A, TT-81 = M922A, TT-101 = M926) and pictures I gather online, it's possible the TT-81 uses a similar motor like the TT-71, which is NOT a coreless motor. If you look at this picture in vintageknobs.com the TT-81 appears to be an electronically more sophisticated TT-71 with similar core motor. I think the TT-101 is a different animal with different motor (coreless) and electronics.

Drawings of each motor in exploded view:
TT-71
TT-81
TT-101

Of course, the best way to find out is for Halcro to take a picture of the motor or innards of the motor of TT81 once and for all. If we see the coils wrapped around an iron core then, of course, it's a core motor.

"Hiho, I can see the light at the end of the tunnel, as regards a report on how the QL10 ensemble "sounds".

Whew! Just reading the travail you went through is adventurous! I look forward to an eventual sonic evaluation of the TT101 comparing to your other DD tables.
