After reading all the posts I could find here I still have not been able to find an exact schematic diagram for the model G50-112II amp that I'm trying to repair. This amp appears to have been mfgd. in the early 90's and has channel a+b, reverb and a parametric EQ. Serial# is 1494. The DC board shows # LC85010 and has been damaged by someone who attempted to crudely remove the IC and lifted the traces right off. I would really like to find another loaded board to replace this one because I don't have any idea about the integrity of the other components on it. Does anybody know where I could find a replacement DC board ? Also I would like to find an exact schematic diagram for this particular amp.
