I found the PCB layouts designed by Mr. wiljj78 in post 100W Ultimate Fidelity Amplifier. Hope this layout is not having errors. Thanks to wiljj78 for the layout design.

I could not find the schematic of HX11

Should I add more output pairs(1943/5200) for 200 Watts in 8 Ohms?

Regards,
Sha

There is a version here: 100W Ultimate Fidelity Amplifier

I've not looked to see if it matches the PCB you have so check it out.

Thank you for the scheme, I think I have most of the components except the IRFs

Between could you please clarify the below.

1. Output power into 8 Ohms(my preference is 200 watts into Ohms)
2. 60-0-60, Ampere rating
3. 30-0-30, Ampere rating

Thanks again for supporting and guiding us.

Regards
Sha
