VPI JMW VTA Base for 10 or 12 inch arms

JMW VTA Base for 10 or 12 inch arms

This base is a uni-pivot type based designed to work flawlessly with our JMW-10 uni-pivot arms. It features a large knurled VTA/SRA tower with a smooth precise feel makes it easy to set VTA/SRA during play.  The base allows changing of arm-tubes in seconds instead of hours for those with multiple cartridges. In addition, a secondary mounting has been placed between the arm rest and the arm lift to greatly improve the arm's rigidity literally making these the only arms that can do VTA adjustments while listening and then be locked as rigid as a solid mounted arm
