Hi finally got PCB from other member who didnt had time to build this amp.
Now buying components and did read that opto for clip must be of certain manufacturer. Wich one work in this design?
He also sent me all info he got trough email from MJ777 like pics of transistor orientation, BOM, display board schem, psu schem and mods like R43 , R39, Q14, Q16.
But is there any actual schematic with values?
And about QMOS1 and 2 on schematic is FDH3632 but on BOM is IRFP260 wich one is good? Why the change?
Also Q17 is BTL169 on schematic and MCR100-8 on BOM ? Why the change?
I would like to learn how this work so any info i aprecilove.
This is what I have so far
I need to put drivers, heatsink, some chips and PSU.
I have a +-55/+-110V psu and +-15V aux supply . What would be a safe procedure to test this amp? What is the steady state current of output transistors ?
I have a big auto transformer so I could start at low voltage for HV and LV like how much?
