Dear Rwd:
Yes, four 360 degree turns.
The release screw is near the top of the tower and bored into the part of the tower that you hold for purposes of turning the threaded tower assembly.
Incidentally, there may be disparate opinions regarding set-up from van den Hul on the one hand, and V.P.I. on the other. The van den Hul site says, very generally with respect to cartridge V.T.A.:
112 Q: Arm manufacturers always advice [sic] to keep the arm parallel to the record during playing. Is this right ?
A: To my experience its not right. What I learned was that in the playing position the arm must always be somewhat higher at its rear end (the counterweight end). A 9 to 9.5 inch arm around 7 - 9 mm higher. This improves the resolution a lot. Works with any arm and any cartridge. What you have to keep in mind is that each record is different. So fine-tuning the spatial resolution is slightly different per record. This can be fine-tuned by changing the distance between the arm bearing and the mounting board.
One millimetre up or down can be enough. But the average of 7 - 9 mm up works always in your advantage.
This comes from http://www.vandenhul.com/artpap/phono_faq.htm#49.
The good folks at V.P.I. e-mailed last night to say:
From our own usage of this combination and from overall industry designs we have found that the Frog usually sounds the best with the back down slightly and the tracking weight around 1.5 grams. The biggest changes in sound when doing VTA happen when you are in the sweet spot. I do not think you are their [sic]. Try lowering the arm so that the back is slightly below level and rebalance your system for this setup.

I am waiting to hear back from van den Hul's U.S. distributor, George Stanwick, who I hope will have comments about the specific combination of 10.5 arm and Frog.
To be continued.
