CT 80 = CT 113 VDC
CT 90 = CT 127 VDC beda tipis ? tapi beda jauh suhu TR finalnya =)) =)) =))

Ini ada cuplikan postingan APEX mengenai skema dan PSU H900:
Full power of this amplifier is not 900W. Power with THD 0,5% is 1200W on 4R load, and 1800W on 2R load. Output transistor must be MJL4281A/MJL4302A for maximum power. For step mosfet use IRF2807. MJL21193/MJL21194 can be used for full power on 4R load.
Transformer minimum 1500VA for one channel 4X40V AC + 2X20V for protection circuit. 2X35A bridge and 8X10000uF/63V for PSU...
Semoga membantu rekan yang mau rakit H900..

hmmm mantab juga
