I need to find service and/or schematics for a MAHA
MH-A103 2-meter HT amplifier.  The unit still partially works. Apparently, a bad ground
on a patch cable has damaged the unit so that it shifts into "over-drive protection mode" at relatively low drive inputs.  Typically, it will shift into "PROTECTION MODE" at inputs of between 0.5 and 2 watts, depending on frequency.

Maha has promised schematics, but never delivered.  Additionally, they had no recommendations regarding service.  BTW, I do know that given the financial realities of repair vs. new amp cost that service is not likely to be a viable option.

Thank you for any help that you can provide.
