ct0517,
Have you ever tried different motors on the VPI TTs you’ve owned?

Regarding motors. I did research on a number of motors, and this included the possibility of using the SP10mkII as a motor/controller, placed beside the TNT; also considered an SL1200 I owned that I used to lend out to people over the years. I came to a dilemma with the TNT. The string/thread drive experiments were a revelation; I was a convert to it, and to improve on the setup I had, required a pulley and platter/bearing system more designed for thread. Ideally the pulley groove needs to be very small due to the diameter of the thread to work best. You can get thread drive to work with a Belt pulley well, as we have discussed here, but the TNT pulley was designed for a rubber belt.
See these pictures. The belt pulley is on the left. The thread pulley on the right

I did own the TNT for a period after acquiring La Platine and did try the Verdier motor with it and vice versa in failed experiments. This was interesting and I can provide more detail if anyone likes.
The Original Platine Granito (like mine) was designed for Thread Drive only. I assume to drum up more sales in later years, Mr. Verdier added the Belt pulley option to appease those folks that wanted it. :^(

flemke - thanks for posting your video. You have an ET 2.0 with the HPM. I like the way you set up your wiring around the plinth area. Very little effect on the bearing. Some go wrong (imo) and try to imitate the Kuzma design with the wires up and over from the cart. This setup I have found effects the spindle/bearing with pushes and pulls. This is ok on the Kuzma design as it needs the wires and air tube for damping. The ET2 however is a different design and does not rely on damping from wires and tubing. It’s an ideal candidate for a wireless bluetooth cartridge/preamp if it ever gets invented. Recommend you get Bruce’ long I Beam. The weight requirement on your own modded I Beam would be cut in half.

I have to tell you that you are a type of Audio enigma to me. You see, from your posts on this forum, you appear to be a big fan of Bruce’;, yet as a vinyl guy you do not own the product he makes that IMO is above all others in design and operation. Did our antics on this thread intimidate you in any way ? 8^0
