100W Ultimate Fidelity Amplifier

[muz1ca89]

hello I changed the resistance 1k5 with 2k2 and 2k7 and i have the same problem. i checked bd139 is ok

Use HX11

Thank you Mr. Mile for the suggestion
I found the PCB layouts designed by Mr. wiljj78 in post https://www.diyaudio.com/forums/sol...imate-fidelity-amplifier-229.html#post3516547. 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.

Replace 1k8 with 470R for more gain...
