Tracking Force Gauges


I have only coarsely adjusted VTF on my cartridge using a Shure gauge and taking into account the ~ 0.3g overshoot some have reported.

I would like to embark on a careful study of the sensitivity of the sound attributes to small deviations within the recommended mfg's range. I'm curious to know what high VTF sounds like compared to low VTF and to find an optimum setting.

To do this I'm interested in your recommendations on digital VTF gauges with 0.01g accuracy.

I've heard about the MyWeigh scale and others. It seems like the my weigh scale is a traditional looking digital scale in that the measuring platform is very wide with the load cell likley centered beneath the platform. I'm not sure that one gets repeatable and accurate results if the cartridge were to be placed near the edge of the platform if the arm can't be moved in such a way.

Any thoughts on accurate VTF measurements?

SirSpeedy, will a gallon of MD 20-20 suffice? Or Boones Farm perhaps?

Opalchip, I have a guage very similar to the one's in your links. The difference here is the the scale we're talking about (assuming the claim is valid) has precision that is a magnitude greater than the range we care about. This extra precision means we are using the scale well within its limits. We know that absolute accuracy isn't as important as repeatability. It also, and most attractive to me, has the feature of weighing VTF very close to the surface height of a record on the platter. I could fabricate a jig as others have done but I'm not sure that it is worth my time to save a few bucks. Though I have no idea what it is, the shipping charge must be fairly hefty if it is coming from Singapore.
For what it may be worth, I have a lab certified 2 gram weight and today this new scale from Singapore read exactly 2.000g nine out of ten times. One time it read 1.998g. Last week, it read 2.000g ten times in a row. It also seems to be very consistent in its readings when used with a cartridge. It may be worth every bit of a C-note.
Agreed Vetterone.

Dan_ed. The force gauge from Singapore is not only less than $100.00, air shipping is included at that price.
Hi Dan - I realize that most of the people posting here are sophisticated enough to know this stuff, and make a decision based on their own needs (or psychology) - but I often like to play the Devil's Advocate for newbies who are reading Audiogon and wondering if they now need to spend $250 on a scale for their $650 Rega, etc. These pocket scales (like the $35 American Weigh type) that are used in the jewelery trade are very accurate - they have to be. A tenth of a carat can be $100's of dollars.

BTW - in my own experience, subtle changes in antiskate have a larger effect on sonics than equally subtle changes in VTF. Everyone's different, but I need about two tenths of a gram change in VTF to hear a really significant change, while less than a 1/10 gm. change in A.S. can make a huge difference to me. So part of my reasoning also, is that I don't think I need a scale which is maybe 20 times more sensitive than my ears.
Two things.Well,maybe three.--Dan,I said cheap(still some good stuff,there),not "crapola".Just kidding.You owe me nothing!
The guage,for 95 bucks,includes shipping!Put THAT in your pipe,doubters!!

As to the business of the Jensen scales.I had one,and actually liked it,though there was a platform for dropping the weigh area.I guess I have no problem getting "ripped" a little.Take a look at,and use some common sense regarding stuff like NOS tubes(I spent big dough,here,and got a nice improvement/revoicing,in my phonostage)etc!PLEASE!95 bucks for a really cute device like this is a MUST,to me!My two other friends who have it love it too.

Best!
