apexaudio ,sir what is the exact input voltage for apex h900 for true 900watt rms output? Is it 110/55 or 120/60? and for 120/60 output PSU has the both transformers out put i.e 40 0 40 and 40 0 40 same ampere ratings??

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

An externally hosted image should be here but it was not working when we last tested it.

Nice work but this is B500

Yes,now it is B500 but normaly it was H900 (on left side you can see the holes for components) but i dont like how it works on oscillo and i let only class AB
Anyway now it work well
I must make the clipping display and it will be ready to us
Thanks again Mr.Mile
