Hi apex...where is the better..2 h900 in bridge mode or h900 tef?For 1500W into 2 ohms U need 2000W transformer, use two PSU for stereo.
Regards
use mjl21193,mjl21194 for the outputs and drivers & you can use two types of relays for the speaker protection relay,(12V)..good sound...enjoy it..
sir Chestap.
i need help,
i have done all the work on your amp, just waiting for njm ic,can you pls tell me any substitude of njm4580,m5218,m5218 AL? its hard to find.
thanks
Do anyone want to DIY something like that?
magnific
I will post schematic for PSU and protect soon.
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... are you still interesting to build this amplifier?
hi i am Andrew Cortez from Philippines i'm going to build your amplifier design, i'm exited to hear and feel its performance as a power full home audio
hello dear sir apex
sameerx1 to do it myself with your schema, but i have thought proper to print pcb materials, the name of my hand there are the non-transistor material as possible, placing the full scheme name and email it thicker Take Care Thank you. email

That's OK, 6k8/2W must be hot.
