vpi tnt still a performer?

Stringreen is trying to sell you on a Classic platter.  At this point I don't know why.  The Classic platter is good enough, perhaps, but it's not the best platter VPI has ever made for a TNT.

A "ribbed" platter doesn't sound like anything VPI has ever made.

IMO if you can't give us more information and a picture of the table you are considering it's impossible to give you any sound advice.

As Audiogon doesn't provide for pictures n its posts, I suggest you find a site to store your picture on, and put its URL into your next post.

Its a 3 spring feet all stock 

Hi oleschool
Owned a modded VPI TNT for many years.
The VPI TNT has something really good going for it - isolation of the motor.
Add in those rubber belts and it produces a warm full bodied sound.
However introduction of the Technics SP10 MKII in my room revealed just how much the TNT’s rubber belts slurred the music. Getting rid of that old cranky PLC, and adding in a VPI SDS, took the rhythm and pace one step further, and closer to the direct drive. So that’s one good upgrade option. You can sell the PLC to recoup some of the money. You will have a hard time getting rid of that extra platter (the other option mentioned) - imo. Something to think about.

Now replacing the rubber belts with thread; that put the TNT on even footing with the SP10 MKII in the rhythm and pace dept. But the Technics SP10 could not match the TNT for its isolation properties.

The problem I found was that the TNT platter/bearing design is not meant for thread; so the thread needs to be changed out every 40 ? records going by memory. This took only a few minutes to do.

So I say keep the classic and pimp it up. Mine ended up with a pneumatic air suspension. There is a pic here.

Unfortunately the audiogon system doesn’t permit me to select just that pic. So see the pic forth row up from the bottom. Good luck

A ribbed platter is VPI. I have a 3 and it has that. It is a very good platter. The 3 should have the air bladder feet and they work good but need to be releveled once a month. A 2 minute job. A very good table, I would not sell it to get a classic. 

" the thread needs to be changed out every 40 ? records"
I have used a silk thread and never had a reason to change it.  Of course you need a speed controller if you use a thread to allow for slippage.  It is well to spray (or soak) the thread with an adhesive.

I guess I stand corrected about a "ribbed" platter.  I would love to see one.  Googling "VPI ribbed platter" comes up empty.  Any chance of a picture?

IIRC air bladder feet were introduced with the Mark V version.  Some were retrofitted to earlier models.  As they proved to be a PITA, they were replaced with squash balls.
