If the remote transmitter uses an electrostatic emitter, it's possible it is burned out, but hard to tell if you don't have the receiver working.

The chassis has been working yesterday in testing and for last couple of weeks, weak response from the hand unit as usual but every function would work if you got it close enough to the set, sometimes from a good distance.
Then all I did was poke around the hand unit a little with the ohmmeter checking things and walk back to the set and - zippo, no response anymore . The chassis pulls in relays when I add capacitance to the mike plug just like it did before (like touching a piece of wire to it) and voltages all check out. And on top of it I think I may have found the actual cause of the weakness, the little round screen in front of the transducer was 99% clogged with dirt and wax so the sound was probably being almost totally muffled. And even now the hand unit ACTS like it isn't dead, I read frequencies off each function and voltages to the transducer. I'm gonna have to leave this thing alone for a few weeks, too ticked off at it right now.
