[Amps] Acom Board

[Mel Friedman]

Just developed a problem with my Acom 2000A.  When amp is first turned on it works fine.  When I attempt to go from OPR on remote to STB the green light does not move. In addition the amp is still in the fired up mode.  If I then push in the red on/off switch, the amp does not go off, but rather the green light on remote goes from OPR toSTB.  However, the amp is still physically in the transmit mode and when I now change frequencies on Yaesu, the display on remote does not change bands.  Lastly, I cannot shut down the amp with the red ON/Off switch on the remote.  I cannot cool down the tubes prior to shut down as I must use the on/off switch on the Acom 2000A to do so.

If anyone has any ideas, I would appreciate some assistance.
