Finally, a clever inexpensive, solution to a Perplexing problem! No more arm removals to insert shims for adjusting the VTA of you phono cartridge. Simply install the Isovert on your rega RB 250 (remove the black plastic push on ring at the top of the threaded base before fitting)  or RB300 tonearm for infinite adjustment of VTA without losing the rigid mounting so important to proper sound reproduction.

NOTE: The Isovert requires a 1 1/8 diameter-mounting hole. This may require enlargement of the existing mounting hole

Installation of the Isovert raises the tonearm 1.75mm from the standard. This is slightly less than the thinnest shim (2mm) that Rega Manufactures .

If  your arm is already at the right height or correct VTA  before installing the Isovert ,and no Rega VTA shims are installed  the arm will be too high  with the Isovert  even at the lowest setting  unless you can lower the arm board. The Isovert should not be used.
