Rhodes Chroma Polaris

I am dealing with a polaris repair right now. The ribbons might be OK and 
show continuity on the exposed parts, but the entire ribbon connector can 
have a hairlin break across all of the traces near the opening in the panel 
just before it enters the panel. this is where the traces aren't exposed 
anymore and are insulated with that green coating. you hjave to look really 
closely to see the fracture. In my opinion, all of these instruments are 
going to experience that problem sooner or later, it's inherent in the 
design. if you don't open the case it might take longer. Everytime you 
disturb that fragile ribbon, it's a problem because it has become so 
brittle.  I have already ripped out the left side membrane panel and 
reversed engineered the circuit. i am waiting for switches that I will mount 
on the panel. I am attempting to repair the right side panel by using silver 
epoxy and attaching wires to new header cables.  It's very frustrating. I 
might just rip out that panel and make a switch ban for it too. But it's 40 
switches, so I'm going to try to fix it with the silver epoxy first.
