Lynn,  

   

Stein sells the washers.  Click on the accessories link on his webpage.  

   

While were on the subject let me confess my ignorance yet again about wiring…  

   

I have a PMA-6000M (mono intercom) that I plan to install.  At some point in the future I might elect to replace it with a fancy stereo model.  Can I use the stereo jacks and cable now with the PMA-6000 but just hook both the L & R wires together on the Audio High side on the intercom?

 Tying the two channels of the stereo directly together doesn't work very well.  Remember that the sound comes from a moving coil attached to a cone. One channel may be driving the coil while the other channel doesn't want to .... big tug of war.  Here's what I do to use a stereo input in a mono system:  I take my radio aux channels and feed one side of the stereo (I wired in a car stereo receiver) into one input and the other stereo channel into another.  The radio will do the mixing just fine, and the intercom will distribute the converted stereo.  If you're planning on the stereo upgrade, don't forget to wire for left/right to all the stereo jacks.  You can plug the mono headsets into the stereo jacks and it'll work fine.  Most stereo headsets have a switch that combines  the L/R channels to allow use in a mono system.

 If this is confusing, touch base off-list
