Riggle Vtaf w/Rega P9 & RB1000. Good idea or not?

I thought of something in regards to using the Riggle Vtaf with the Rega RB1000 and P9. If one used the Cartridge Man Isolator between your cartridge and head shell of the arm, then the extra height of the Vtaf would be compensated for and there may be no need for the use of the shim the comes with the Vtaf.

I put it on my rb300 arm on planar3 and love it,would never buy another table without vta adjustment .

Jbcello - did you go through with the Pete Riggle VTAF mod on your P9? If so, what was the result? I too am a P9 owner. With thanks

Hi Jbcello,

I would like also to have your impression about the Pete VTAF...I have a P9 too and I am thinking about this device;

Thanks,

Please, any comments ? I am trying to install the VTAF in the RB1000 / Rega P9 and I am facing a lot of problems concerning the tonearm height. Even using a higher spacer between the cartridge and headshell, adjusting the lift mechanism to the lowest level, the tonearm is still positive in around 3mm.
Actually the spacers supplied by Pete are supposed to be installed only on the rear of the cartridge top surface and I am little concerned by that since by adding a spacer only in one are of the top cartridge can alter the stylus angle. As a result, I am still trying to use a spacer right now that covers all top cartridge surface.

The VTAF adds 11mm to the total tonearm height which seems to high for me. For sure I am in touch with Pete, but any help from somebody that has already used it in a Rega P9 / RB1000 ( or any Rega table with 3 points tonearm ) will be very helpful. I am using the VTAF with the extension supplied by Pete ( in order to avoid to make an addition hole in the plinth ) which add an extra height of around 4mm in the total VTAF heigh, comparing to the "normal" VTAF.

Thank you,
