Vintage DD turntables. Are we living dangerously?

Correction - the lead-out starts at approx. 60mm and the record goes to 160mm, so I guess it would be more like 105mm from the spindle.

I have a few records that are recorded much closer to the label. You'd have to experiment. VE has a free download protractor called Chpratz. It's a calibrated straight line with a grid all the way and calibrated with distance from the spindle.

One thing that peaked my interest was a comment by one of the reviewers. He thought the shorter version of the arm sounds better - less resonance and vibrations. I was thinking of getting one of those straight arm DJ tables just to try it, but I couldn't bring myself to do it.

Instruction on setting up the RS-1A tonearm using underhang scheme. I believe the arm uses the tangential point (or reference point) right in the middle of the platter which is 3 inches away from the spindle about 76mm radius.

You can use that as a starting point to experiment with the SAEC or other available arms.

Hello Halcro,

Based on your experience, which JVC motor has morer torque,
The TT-71/81 or the coreless TT-101?

Thanks!

Doron

Hi Doron,
According to Vintage Knob...the TT-81 has 1.3Kg/Cm starting torque against the 1.8Kg/Cm for the TT-101.
I don't know how that relates to perceived performance as both decks are consistently immune to the the effects of 'stylus drag' even under three cartridges running simultaneously...😍
I also can't hear a difference in performance between the two decks in my system.....
Regards

fwiw, the manual for the tt 101 states 1.2 kg.cm as the starting torque.

Just for giggles, I looked up the starting torque for Lew's sp10 mk3: a whopping 16 kg.cm. But the platter for that weighs as much as the entire tt 101. So both tables reach operating speed in under 3/4 sec.
