How to properly set VTF??



Hello there.

Just wondering which is the proper "placement" of the gauge to set the VTF for a cartridge. I use a digital gauge and normally fine tune by ear.

Method #1
Place VTF gauge directly on the turntable playing surface.

OR

Method #2
Place VTF gauge "outside" of the playing surface beyond the records edge.

I set the VTF at the recommended 1.96g using method #1. I then tried the #2 placement and the measurement read 2.14g for a difference of 0.18g

The only explanation I can think of that attributed to the weight difference is the anti-skate setting. On my arm (Tri-Planar) the anti-skate kicks in when the cartridge is on a playing surface, outside the playing surface the anti-skate is very minimal.

Which method do you think is best or is it arm dependent?

Cheers!

Bob, I agree with most of what you're saying. However I do believe that arms such as the 2.2 is it possible to get repeatable VTF settings provided the scale used is good enough which is what SirSpeedy is telling us. I am betting that I could do this with my RB-250 that has a Mitchell weight installed with the micrometer-like VTF adjustment. But first I would need to invest in the $800 Winds (OUCH!). If we're talking about a Vector, or TriPlanar, or perhaps your Stax (I'm not familiar with the VTF machanism on that arm) I will agree completely with you as it is damn near impossible to move the weight in such small adjustments on these arms. All this being said, I think we do all agree that getting it really close with the guage and then adjusting by ear is the way to go.

SirSpeedy, I've only played extensively with a 103R and a Benz Glider. Both of which do no seem to react much to VTA over a fairly wide range. This used to drive me crazy because here I am trying to listen for changes and they just never happened on both the Vector and 2.2. I've since learned from others that these two cartridges are not real sensitive to VTA and I guess I've proven that to myself.
Sirspeedy, sounds like you have a winning formula. I am sure that your formula for dialing in the vinyl playback would work just as well with a 0.1g resolution VTF measurement, however! Sometimes just adjusting the tone controls (ee gads, tone controls) on your preamp or adjusting the phono input parameters (capacitance, resistance etc.) will give you the same results as 'playing' with the VTF at 0.01g intervals AND is much more repeatable.

Dan_ed, 'All this being said, I think that we do all agree that getting it really close with the gauge and then adjusting by ear is the way to go.' Yes.
We are disagreeing on how close one needs to get before adjusting by ear.
BTW, have you ever you checked the repeatability of your gauge? Try measuring the VTF every day for the next twenty days without touching or adjusting any of the parameters on the arm. You might be surprised by the different readings you get every day.
With respect,

Heck, Bob. The $35 digital guage I have now will hardly give me the same results if I measure VTF one right after the other only seconds apart. :) I'm not sure if that sucker is any better than my Shure balance.

Oh, yes. I would expect that the VTF could change from day to day. I was arguing only that it is possible on some arms to adjust to that .01 fairly repetatively.

I certainly wouldn't mind being wrong on this. I'm planning on purchasing a Winds soon and this could save me $200.

BTW, does anyone have any feedback on that digital guage being offered under the cartridges for sale? SirSpeedy mentioned it a few days ago but I've not been able to find out much about it. If it is that good it could save me another $500.
dan_ed, And I am sure that the Winds repeatability will not be much better than +/- 0.02g, ie. that it will vary easily every day by that amount. just not worth the money.
Stick with your Shure gauge and your ears.
