Im trying to repair this earthquake amp model 200dhc. few of the power supply transistors are defective so I'm replacing all of them .I do have the originals in stock but while checking for gate singal I'm getting 13v exactly as my power supply .Fets are being driven by a 8 pin Ic and the model number has been sanded off ,I'm guessing from the factory .I don't have that much experience but i believe the voltage is too high .If anyone have idea about this amp and the Ic model please let me know
thank you
