AD8500 - 1/4" Mono To Non-Conductive Tip 1/4" Stereo Adaptor

1/4" Mono to Non Conductive Tip 1/4" Stereo Adaptor

Although this may look like a stereo cable, it is internally a mono!  This adaptor is required for stim machines made prior to May 2000 that used to take a Mono plug but are now required to use an FDA compliant (non-conductive tipped) stereo cable.
