Greetings,

I have a TONO 2M-190G ( 2 meter amplifier) with low output (+- 40 watts out at 5 watts in). I suspect the driver transistor but can not find the circuit diagram anywhere. My workshop have the proper equipment to do component level diagnostics (it is not a complicated circuit) but I prefer the schematics. Any help appreciated.

I am not familar with this amp and Google gives no clue.  When I have a circuit and no info, I draw my own schematic by visually tracing the parts and wiring.  A driver circuit won't have more than a handful of parts.
