VPI anti-skate device

I've been trying to adjust this thing to get optimal results. It seems that when I adjust to for less anti skate, the adjustment also causes less counter-balance for the device and it topples over towards the tonearm eliminating any anti-skate benefit at all. It can also bind the tonearm and cause skipping and mis-tracking. Perhaps I'm not installed it correctly. I have it mounted in the junction box screw hole closest to the tone arm (JMW9). If I mount it so it points straight out towards the front of the plinth with the notched portion with the two o-rings sticking up, the tone arm will bump into it during the playing of an LP. If someone with a Scoutmaster with the JMW9 arm has this device installed and working properly would post a picture or two at several angles maybe I can get this thing to work properly.

I had a 9 Sig, and now am using the 10.5. In both cases the device worked without problems. I have the rubber washers about 1/2 way up its arm. It never interfered with the tonearm except in providing side thrust compensation. If I send a picture of my 10.5i it will not help you with the 9 - the 10.5 is set up a bit differently. If you send a picture of yours Arnold, I might suggest something I see may be misadjusted. When the unit is installed properly it works as intended.

Arnold,

Have a look at the VPI web site under "Products and Accessories", "VPI- Accessories", "VPI - JMW-9 Anti - Skate Assembly". There are a couple of clear pictures located on the page.

Here are three pictures:

As you can see, in the second picture, when the arm is in play, the mono filament reaches it's maximum length before you reach the end of the LP side.

Arnold,
It looks like you have it set up correctly but the string is not long enough. I have a 10.5i arm and made my own string out of 4# test fishing line. I also do not use any O-rings on the outboad arm and only one on the upright arm with the loop of the string just resting on top of the O-ring. The loop is as high up on the arm as I can get it for the minimum of anti-skate. I made the string to a length so it touches the top of the pivot point when the arm is at rest, with it this length it is activated as soon as I move the arm but will not flop the devise over when the cartridge is at the center of the record.

Good luck,
Mike
