VPI TNT balancing

I�m currently using a VPI TNT 6 HR turntable (JMW 12.5 tone arm) along with a Shelter 501 cartridge. I have carefully leveled the turntable and rack using the small VPI level as well as a longer level (about 18�) just to be certain all is OK. I periodically go through the set up process to make sure that none of the adjustments have changed. So far so good. Here�s the problem � at least I think it�s a problem. In order to get the proper tracking force, the counterweight is virtually at the extreme end of the tone arm. Although I have never had a problem with tracking, the arm is rather unstable when cued on and off an lp. My manual indicates that the counterweight should be as close to the pivot point as possible in order to make the arm more stable. I suppose I could add another counterweight, but I�m afraid that will be way too much weight on the non-cartridge end. Has anyone had a similar situation, and if so, what was the solution? Thanks.

I did sacrifice a bit on the cartridge to get the rest of my system in place. I'll be looking to upgrade the cartridge within six months or so. I'm happy to hear suggestions as to replacements.

As to my current situation, my dealer is going to contact VPI, but I understand they're on vacation for a couple weeks. Thought I would see if any one here had encountered this problem.

I made one error in my response to you. That was there are many "mid-fi" users here! NOT! Some people here own Cartridges, that cost more than my entire Turntable-Arm-Cartridge! Sorry for my mistake, there are many here who forgot more than I know. Mark

Add a three gram weight to the headshell. That will allow you to move the counterweight closer to the pivot point which is always a good idea.

Good luck.

Hello Wendell, Sorry, but this doesn't sound correct to me. If you re-read the original poster's comments, it sounds like he's saying that his counterweight is already at the very end of the Counterweight Stub (away from the Pivot) as it is.

Adding a 3g Headshell Weight will then mean needing even a more heavier counterweight. I'm thinking other counterweights are available from either VPI, or other parties if needed. Mark
