The pcb has several errors, I'm still analyzing it.
Now if it's okay, you have to try, and what did you do this design work?

I do not understand
i just finish my H900 but i let just class AB because i do not like how class H works
The cage is an original old amplifier Renkforce HVA-9080that was damage and i receive only the cage.
PSU is the original one +/- 67V and 800W consumption
On output i have 34Vac RMS/4 ohms on oscillo with limiter even i put 3V on input and without limiter i can have even 40Vac RMS but with clipp
I observe with this main voltage i don't need a fan for cooling,on 4 ohms works perfect!
Thank you APEX
