Is there a best cartridge track force gauge?

I have a Jennings JS-50X scale from www.rightonscales.com go to pocket scales it's $58.99US and is good to 50 grams in .01 gram increments. On my VPI I use two cassette cases (one on top of the other) below the scale and it comes to the perfect height. Can't beat that price.

First, I set the VTF to 1.5 (for shure V15) using the dial markings of my TT. (My TT, a Sony PS-X800 has a servo "Biotracer" arm where the arm is automatically balanced for zero downforce each time you start the TT, and then the downforce is applied electronically...very accurate).

Then I play a tracking test record, and reduce the downforce according to audible results. With the linear tracking arm of the PS X800, the resulting VTF is about 1/2 gram...much less than the same pickup in a pivoting arm, and less than half what Shure suggests.

So, I am in the "by ear" camp, with the provision that the test is done using a tracking test LP.

I second dougdeacon's advice. A good, ditigal .01g scale can be purchased for approx $30 on ebay. I fabricated a platform for the stylus from an old credit card and used double-sided tape to attach it to the scale platform. It is a snap to use.

I think that Albert mentioned having experience with some type of digital tracking force gauge in someone else's system. They couldn't figure out why the system sounded so out of the ordinary until they verified the tracking force. The results obtained using the digital gauge were WAY out in left field, hence the sonic problems. I don't know the details of this specific case in terms of make / model, but it's always good to have some way to appr verify that you are in the ballpark before fine-tuning by ear. Sean

There was a time when pickups tracked at 5 or 6 grams. Yes, really! In those days the VTF could be set by a sensitive finger, and a nickle coin, which weighs exactly 5 grams. Put the nickle on your finger, then substitute the pickup. True story.
