In a wrong resistor value and correct, now not operate well!

Apex Thanks, I'm ready to send the photos but I'm without internet at home will soon send you.

Hi apexaudio
Thank you verymuch for all schematic and PCB for diy.
And please show project PA amplifiers new design with 2SA1943/2SC5200 bipolar output tranzistors and IRF2807 mosfets for step amplifier work in H class 0,+/-60V,+/-120V.
Thank you.
Best regards.

I share many design, some are prepared only for diy, why you interested specialy for this amplifier? This amp is based on "100w ultimate fidelity amplifier" with H-class rail. I suggest you to build "100W ulti", and hear do this sound like to you. You can use H900 with IRF2807 on 0,+/60V,+/-120V.

Hi Valenca,
I like to see photos.

Hi apexaudio
Part high speed power MOSFET and IGBT driver (IR2117)( Use for Crown K2 & Zeck PT Series & class H other).No have on hand and to search for elctronic store shop in the country part no have (For use order part out off the country only and lose time many ).
And project PA amplifiers design with 2SA1943/2SC5200 bipolar output for step amplifier work in H class 0,+/-60V,+/-120V use for general electronic component part.

This step driver not well tested, and I will share this schematic when I'll be sure that's work ok. I suggest to use step driver with TL072.
