Madfloyd...that depends. If the internal weight is full forward, you can make the VTF lighter, or full back you can make it heavier. Someplace in between it is fully adjustable. In any case however, the azimuth will not be affected. Mine is fully forward, so to make the VTF heavier, I would need to move the main counterweight, and then check that the azimuth is again level. I check azimuth by using the rod. I have 2 Cardas blocks with washers glued to the blocks at the proper height, so that when the cartridge is resting on the record..just a hair above it...both ends of the rod will be just a hair above the modified Cardas blocks which are placed on either side of the cartridge and on a record just under the ends of the rod which is positioned on the headshell. (What a sentence that was)
