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

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.
