Another suggestion for cleaning dirty relay contacts (should that be the
problem) is De-Oxit by Caig chemicals. Hs worked very well for me in the past.

Ok, thank you to all of you sending information.
Regarding the Muted receive with in OPR mode:
So far, I have determined that it is NOT external to the Amplifier. I
removed the external relay cable, and the muting / relay issue still
occurs. Also, someone sent info that the LED should NOT light if the
transmit is not keyed. Perhaps that issue is the same as the relay
issue - a grounding problem.
Now, I have to learn how to make sure the amplifier is safe to open
and start internal work.
Thank you again to each of you who have helped so far.
