Connex 4800 DXL EPT690010Z board. This board in it's most common radio would be the Galaxy 959.
Some history on the radio how I got it. It was plugged in backwards Two finals were blown. I do not the two problems happened together. The radio now has 2 new finals and a new driver installed. All traces look good. TR50 and TR51 check good. The radio has great receive and very loud. But I have no transmit audio on side band and AM. Tracing with a oscilloscope I see a little movement all the way...
