900W H-class PA Amp with Limiter

[wely]

Thanks kandimba,
but in my place very hard to get diode like this ZF15,
Is there a replacement for this diode sir?

I just need to find this Zf15 and sfa1603 or mur1620, then i can start to assemble this h900.

Regards.

Use this PSU per channel, but in commercial brand PA amps is usual to use 8x10000uF for two channels.

what is the maximum voltage of the H900

As per scheme With good quality component i think apex h900 can handle 120vdc
