Default 900W Class H PRO Power Amplifier.

Hi all!
This is not my first amp, but it's a first two-rail amp in my series called "Nataly".
Specs:
Nominal power - more that 900W, 4Ohms
THD on all frequency response - less 0,03%
THD on 1kHz - less 0,005%
This amplifier was made and discussed on Russian forum: V.2013 PRO-
Project homepage (in Russian language) - ????????? ???????? Nataly - ????? ?? ????????????????
With respect from Russia
Vadim Mogilniy.
My nick on Russian Sound forums - Waso.

Ok.
Last edited versions of files. PCBs are made for single-sided material.
Russian opto-pair AOP124 may be changed with VTL5C2, VTL5C3 with difference of pins. Russian transistor KT815 may be changed with BD139, 2SA1837, ets...
