I mean you measure the distance between the playing surface of the LP from the plinth (with the platter and the mat underneath). Remove the platter, the mat and the LP. Place the digital force gauge in the "platter" area on top of a stack of playing cards and adjust the height accordingly to the same distance you measured earlier. Wouldn't this give you a more accurate VTF measurement than placing the gauge on the platter?

Yes ...

As I understand it, you should be setting the VTF with the stylus in approximately the same horizontal plane as the record surface. (Say, a 180gm LP, if you have different weights ranging from 130gm to 200gm.)

So, unless you have Wally's electronic stylus guage with its cunning acrylic arm which extends over the edge of the LP and down
like this: ---|_
you need to measure VTF off the platter.

I made up a block of wood so that when the VTF guage rests on it, the pad for the stylus is at the height of the record.

I have a Spacedeck with the armrest/ lifter right close to the pivot assembly, leaving the area foraward of that and next to the platter open for using an old tin can and a wooden pad (actually one of those back to the land boutiquey soap dishes) that when stacked right next to the platter make a pedestal putting the gauge right at platter surface level. Works fine. You could do it stacking CD cases too, that would at least make them good for SOMETHING worthwhile. `,;^)

. . . Actually , thinking about it, the gauge is cut away in a concave arc along the side making it look as though sitting right next to the platter is what it was designed for. . . . D'oh! And here I thought I was being SO smart . . ..

I suppose you could do what you suggest, but what is the advantage? Transposing a measurement is usually inferior to a direct measurement, and is avoided, without exception, by all I have ever met who work with measurements.

So you do the measurement , then try and figure how the results match areas in measurement in another location. I would rather work out any measurement problems at the primary location, rather than create Two areas of potential mistakes.

Besides, it's set by ear in the final adjustment, no other tools will work as well. I never sweat it myself.
