Hi,
Just got a Mooer Little monster AC, 5W single ended EL84 guitar amp.
I've tried to trace the PCB and draw the schematics, it's incomplete, maybe some mistakes here and there, but since I didn't found anything about it's better than nothing
I've made some measures on resistive load, it's almost linear from 200Hz to 8k, output transformer looks like a good one. Clipping begins at 7V - 8 ohms (3W)
EDIT : added inside pics. Yellow caps from the first pic added by myself for testing purpose. First mod done by increasing "mellow" cap to 47n for more bass. Amp provides almost a flat response starting from 150Hz instead of the default 300Hz.
