Apologies to anyone if I came on strong. I just love my TT too much. My motor had a circuit board bug and I just got it back from Chris Brady. He turned it around in one day and installed the $70 Signature II board upgrade for free! Hugs, kisses...
Jyprez,
Agree you can get great stuff used, better than anything new for the $. That's how I got my 901, otherwise we couldn't have afforded it. (Also my CDP and amp.)
If your Gyro is portable a side-by-side would be great fun. We could probably swap arms pretty easily, to make it as apples-to-apples as possible. I'd offer to return the visit but an assembled Teres is not easily transported. Tilting it even a little would spill oil from the bearing.
BTW, did you hear John Michell just passed away? Sad new for analog lovers, RIP.
Psychicanimal,
I don't know if the Teres project considered DD or not, great question. Eldartford suggested the same thing a little while ago. Controlling stylus drag is the goal of course. DD "should" do that very effectively, assuming other problems can be avoided. Since the Teres motor is claimed to be virtually noise and vibration free (as much as that's possible) it seems like an obvious candidate.
Sayas,
After testing many materials, mylar belts proved the best performers on Teres, Redpoint and Galibrier TT's. VHS tape was a close second. The advantage of mylar vs. rubber or neoprene is its dimensional stability. A non-elastic belt provides a direct torque linkage between motor and platter, instant resistance to that stylus drag Albert loves so much! If slippage can be avoided, a rigid link best emulates Psychicanimal's direct drive. Obviously this requires a motor that is vibration-free and speed-stable, so that dampening is not required. The Teres motor seems to fit the bill, and I expect the Redpoint/Galibrier motors do also.
You can check my thread "TT Drive Belt Comparison" for a description of the sonic benefits of mylar vs. the silk string Teres used to use. Also Agaffer's recent thread.
I've never observed any static buildup between my belt and platter. Perhaps because the Teres bearing is grounded? Perhaps because my wood platter is a poor conductor? Don't know if this is a problem for a Teres with an acrylic platter.
Jsonic,
If you're still following this very hijacked thread, are you old enough for some of this? How can a nude stylus be in drag?
