VPI Tnt Questions

I have a TNT Jr. w/upgraded motor (single flywheel) super platter, SDS, Cardas interconnects, Benz Glider, JWM Memorial (I think 10) and it does sound absolutely wonderful (on Britestar Bigrock loaded w/sand on Billy Bags Pro Rack).

2 questions-

1st - how do I know if I have a JMW 10 or 12? Is it the length of the armtube/headshell or all the way back to the end of the armtube after counterbalance weight? 2nd, I know I can upgrade this rig up to a TNT Mk5. Anyone know if anything is involved, other than the feet?

Appreciate your help.

I started with exactly the same set-up. Don't waste your time with the Mk5 upgrade. Switch from rubber belts to thread, substitute Stillpoints for the stock sprung suspension, and decouple the sandbox using springs as per Promethean plaform.

Heavy sewing thread, carpet or button thread, cotton polyester or polyester. Try to use thread that's not slippery through the fingers. Practice with a sandard double knot to arrive at the correct length & tension. Then cut the thread, measure its length, and start again with a fisherman's blood knot. This circulates without pinging. After careful tensioning, you will hear improvement using thread on both spans from flywheel to platter and from motor to flywheel.
