Does anyone by chance have any info on this amplifier such as a schematic diagram? I have a resistor getting hot, the unit still puts out power but obviously has an issue. I have been over to CB tricks but nothing listed as just a M4000.
Hello did you ever find out what resistor that was the color code on it or what have you mine is completely burnt out and it prevents it for cleanup or doing anything so it was definitely has to do with the key up circuit.
Hello, I need repair a M4000 amplifier, but I can't find information such as the schematic diagram or similar, if anyone has that schematic diagram, I would appreciate it. Or if anyone has images of the main circuit board.
the amp looks like it was modified and doesn't work.

thank you
