Kang karso, kalo mau gede lagi h900 dimodif pake 3 step ct-30-60-90vac pasti mantas

tegangan tingginya beda tipis sama h900 ya?

tegangan tingginya beda tipis sama h900 ya?

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..

APEX H900 pake ic drive IRF2807  tr  final MJL21193/MJL21194 MJL4281A/MJL4302A mantep mana ni sama kali yach kang

[bintang sound]

yoo kita priksa mana yg ok
