Hello, I have a problem with this amplifier, does anyone have a diagram of the inverter or the whole amplifier?
I have a problem with the same amplifier. The customer himself replaced the inverter transistors and literally burned down again. All items checked. However, the inverter does not work. Looks for IRFP064 control signal too weak. I don't see any burnt path. It is possible that it is hidden under the adhesive or trafo. According to the meter, there is power and GND on the respective legs of the control transistors. If I skip the D669 and D649 transistor driver. The inverter starts.
