VPI anti-skate device


I have a VPI scoutmaster wtih JMW9 tonearm. I purchased the add-on anti-skate device and I am having trouble setting it up. I installed it according to the directions I found here: http://www.elusivedisc.com/prodinfo.asp?number=HW-JMW1015

However the device is is interfering with the full rotation of the tone arm. The left side protrusion of the tone arm hits the anti skate device. Can some one with a JMW9 and the antiskate device take a picture of their set up and email it to me so I can see what I'm doing wrong?

I have been playing with the anti-skate for the past several months with my 9 Signature tonearm. I am not using any twisting of the tonearm leads.

This is a picture of how I have the AS setup on my TT. I do not have an original at this time so refer to the link. I find this positioning works best as you can control the amount of swing of the device. I don’t think I would ever configure the AS device as pictured in the Elusivedisc information.

Since this picture was taken, I have removed all the rubber washers on the horizontal post as I found they added too much AS. If you have the metal weight on the AS device, I would remove it as this provides WAY too much AS and find some of the washers locally or contact VPI and have some mailed to you.

If you want additional pictures, let me know and I will snap a few more.

Stringreen, as far as I know, the Nordost tonearm wire is silver plated copper with their proprietary mono-filament and FEP tube insulation. I have not found any mention of the tonearm wire being solid silver. Regardless, I do not want to put any additional twists on the wire.
Actually, I have been optimizing the AS these past months to achieve the best sonic characteristics from my setup. During the beginning of the process, this also included other tonearm setup parameters. Thanks to all who contributed to the ZYX cartridge optimizing threads; your comments were of great help.

Even if the tonearm had a ‘dial’ to adjust the AS, I still would be optimizing the setting. Would it have taken this long? That’s hard to say as I make an adjustment and enjoy listening to the music, then may not play LPs again for many days.

What I describe in the previous post is most likely what I will be using long term; the AS device attached like in the photo without any washers on the horizontal arm and the line attached to the top of the vertical arm. Have a look at the VPI web site as they have several pictures from different angles.

I have tried disengaging the AS device with and without the wire twist. I think I will keep the AS device engaged with the minimal amount of AS it now provides. Like Stringreen, I prefer the AS engaged for the reasons he describes. Thanks Stringreen for confirming what I was hearing in my system.
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.
