Hello Sir Apex , is that right that h900 output transistors 2sa5200 and 4300 i guess are powered from the MV in the schematic that would be 55/60 volts and the step driver from 55/60 volts too?
and when the output sags the supply rail the step drivers 55 volts kicks in to stabilise it ?
Have I got it right?
