Vintage DD turntables. Are we living dangerously?
I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

If anyone was interested in an SP10 Mk3, this one may be better value as it includes tonearm and base... |
Halcro. I re-read my last post and realise that it could be misinterpreted. Clarification here... BT suggests that when accessing speed accuracy with a pivoted arm, the measured performance is inferior to the actual performance. This due to the geometry of a pivoted arm. Since you have a rig with three different arms, it would be of interest to run three sequential tests to see if there are any measured differences. If there are, maybe we could infer that the TT-101 is actually better than the readings indicate. |
Richardkrebs, The measured performance is inferior to actual performance? Wow and flutter can only be measured with an arm/cart. Timeline measures or illustrates absolute speed. Henry has shown that absolute speed doesn't deviate when using 3 arms simultaneously on his Victor. W/F is measured with a test record 3150Hz tone. Output is checked for deviation from that frequency. I think Thigpen must be referring to low torque belt drives, in which case a gnat landing on the arm or platter might upset speed stability.

10-23-15: Fleib1. There is no such thing as absolute speed. Speed is relative. 2. Wow or flutter can be measured with a rotary function generator connected directly to the platter - this is the method Thigpen uses. 3. Using a record with a fixed tone is prone to error. Any eccentricity or imprecision in the surface of the record will generate wow or flutter. 4.The timeline only measures the arrival of a single point on the platter at the same place at each time. It does not measure what happens in between. If you take points 2 and 3 above into account, then when playing records there will be more wow and flutter generated by the arm/cartridge than the TT itself. If you want to relate Direct Drive speed stability to sound quality consider this: Analogue wow and flutter is similar to digital jitter. Testing of digital systems as regards temporal errors and the effect on sound quality has yielded the following - 1. The lowest level of jitter that affects sound quality is 5 nanoseconds. 2. Using sine waves for testing showed most people could hear errors down to 10 nanoseconds. 3. On recorded music people could here down to 20 nanoseconds. I have seen some studies that suggest temporal recognition in the brain is triggered at around 4 nanoseconds. There is no way that the error correction circuitry from these vintage decks is fast enough to be inaudible. If the listener thinks that their TT "sounds" more speed stable than anything they have heard before, then their perception of their current turntable on its relative merits is limited to a relativity to the inferior tables that they have previously used in that particular system. |
