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.

TT81 for others, maybe. I've got DP80, L07D, SP10 Mk3, Lenco for "back-up".

TT101 is looking good. I am leaving it power up. Your quite right that the innards are a veritable rat's nest. I have observed that it is difficult to pack all the wiring back into the metal canister, after working on the circuit. In particular, the AC cord has to be folded just so, otherwise it won't fit. Plus there are all those interconnecting wire harnesses. My hypothesis is that the workers who built these things knew precisely how to lay out everything for final assembly. Then, after 30 years of aging of solder joints and PCB traces, we come along and take the tt's apart and cram them back together when work is done. It is my observation that incorrect routing of the wiring harnesses and AC cord followed by "cramming" can cause the various PCBs to bend a bit, thus putting stress on solder joints and tracings. I would bet this has a lot to do with our problems.
"Your" = "You're", of course. I hate when I do that.
Henry, Can you make me one of those free-standing cradles for my TT101? Who makes your arm pods, etc? Based on your first hand inspection, do you perceive that the TT101 and the TT81 have exactly the same motor? It looks from photos that the TT101 motor might be different in size or in some other way from that of the TT81. I know they are both coreless types.

Hiho, I can see the light at the end of the tunnel, as regards a report on how the QL10 ensemble "sounds". I am dealing with some amplifier problems that appear to have been resolved. One amplifier for each of my two entirely separate audio systems has been "down" on my workbench.
To short-circuit the hijacking of this Thread any longer.....I have re-awakened the 'Vintage DD-Are We Living Dangerously' Thread.....

Lew, will Email you shortly re your questions.
Yep. I guess my posts on the vicissitudes of the TT101 belong in the "Living Dangerously" thread.
On topic: The well seems to have gone dry as regards posting of Timeline results on this thread. Given the many months of its existence, one would have thought there would be more videos by now. When I finalize the modifications I am making to the QL10 plinth and arm board, and then put the QL10 back into operation, I will test my own TT101, see if can do what Halcro's did.
