  I've had strobe speed problems and VPI has been quite responsive to e-mails. They note that lithium grease in the flywheel sometimes thickens and slows the flywheel, less so once warm. They recommended a bit of WD-40 to thin the grease and this resolved the issue.

  Thanks to all for helpful comments - the slow speed does correct after 'warm up' of about 10 minutes - I'll post any reply from VPI as I have emailed them. And yes I'll try a single belt to the platter :)

  I own the HRX. I assume you have the HRX dual motor on the TNT6HR?.

  I guess you all ready know the VPI supplied strobe is useless - the KAB is good.

  I would have to admit every time I measure the speed it is off. Not sure why, but the belts do slip a bit. nowhere near as much as the my old TNT V hot rod.

  I don't really notice it that much, until I obsess about it.

  Why do you have two belts around the platter?. maybe that is doing something to the speed.

  If you find out, please let me know as I would like to measure the speed once a mnth and have it be the same of close to it.

  must be something in the aussie air.

  see what happens. Take the belt off and just run the motor by itself. Keep your eyes on it. Is it slow?? Try to isolate the problem. Contact VPI first thing in the AM and ask them for suggestions. They have good customer service. I hope my suggestions make sense. I never had to do all these myself at all.

    Thanks for the suggestion - good idea save here in Oz the voltage is 220V which might well burn out the motor hence the need for the SRS.

  Slamming the TNT in this forum is not going to get your problem resolved. I don't own an HRX but I do have a TNT with an SDS.
  I can tell you that the speed is spot on and rock stable.

  The motor torque is low, but that is the nature of the TNT beast. Your HRX, I believe, has a bit more torque than the standard variety TNT since it has the dual motor unit.

  Did you test the SDS? The calibration instructions are very straight-forward. Unless the term RTFM applies here.

  By the way, adding to the number of belts on the platter will only make the sound of the TNT worse and will not accomplish anything with regard to speed accuracy.

  Good luck with your "upmarket" irritation :-)

  Cheers,

    I am in no way slamming the TNT - I am surprised by your vehemence. I am simply asking for suggestions from more experienced inmates as I am perplexed by the problem and this is my first foray into VPI gear. And no it didn't fall off any truck but was bought at full retail price from the authorised Australian dealer.

    I think the build and quality of my TNT 6 / JMW 12.5 / SRS is exemplary which makes me even more perplexed.

    As to high end irritation - yes I do get this from time to time and I am sure many others do when we pay astronomical prices for gear and then have to find work arounds for problems (like a strobe disc for 60 Hz inlcuded in an export to a 50Hz country) that 'lesser gear' often doesn't have.

    I will certainly email VPI but often find users more helpful than manufacturers. Incidentally, since posting, I did find description of a similar problem in EAS (Dec 2005) where a Scoutmaster had a faulty motor.

    As to RTFM I might add RTFP as I too have a TNT (like you) and not an HRX and I used two belts to the platter as that was what was supplied and illustrated. As to calibrating the SRS I did RTFM and the only calibration there was for changing the output voltage - the problem isn't one of slow start up but incorrect speed for around 10 minutes.

    Thanks for a provocative reply :)

      Give the bearing some time to break in. Does speed stabilize after a few minutes of warmup?

      I apologize if I mis-interpreted your post. It sounded like a slam to me, but perhaps I was just cranky :-)

      I have found VPI's customer service in recent history to be responsive and generally good. The fact that the table goes off speed after warm up is certainly odd. Perhaps it is a part in the SDS that is failing.

      I hope your problem is resolved. Once it is resolved, I suggest you try running the TNT with a single belt rather than two and listen to the change. You might prefer the change.

      cheers,

  On start up, your SRS is supposed to start at a higher voltage and then drop down once the platter is in motion. I believe mine starts off at 115 volts and then drops to 72 volts. Double check to see if it functions like that. A drop of oil on the motor may help also.
