AM-MU-2A intercom amplifier
When hunting for gremlins in the audio circuits of my Grumman Tiger, I tracked them down to the intercom amplifier. It's marked AM-MU-2A and has no other information except a serial number. Does anyone know the manufacturer - or, better yet, have a maintenance manual or schematics?
