OK. I can give you my personal email.

Bottom of PCB.
I think junior meant bottom copper layer in B/W in pdf format for etching.
New version:
THD 0,05%@1Wrms@8R0@1KHz
THD @100Wrms@8R0@1KHz = cca 0,1%, PSU +/-45VDC
SlewRate cca 50V/usec
Bandwith 2Hz-520KHz (-3dB)
SNR cca 106dB
Shouldn't the drivers be on the main heatsink?
Your PCB also has different components than Mr. Apex's schematic. Did you make modifications to it? If so then it would be a good idea to post the updated schematic as well.
No
There is 2 versions of AX9.
First schematic in post #10156,PCB #10167http://www.diyaudio.com/forums/solid-state/164093-100w-ultimate-fidelity-amplifier-post5374014.htmlhttp://www.diyaudio.com/forums/solid-state/164093-100w-ultimate-fidelity-amplifier-post5373747.html
and second (Dragan100 mod) schematic in post #10183,PCB #10191.
Hi to all
today finished my work Ax14
can you tell me if I set the correct bias?
measured on the resistance of 0.22 ohm, 15mV

An externally hosted image should be here but it was not working when we last tested it.
Mr. Mile,
Can this super simple softstart work for your high power amps? Like BX-22 and SR 200 etc?
Very few components.
Ckt is from TI app note

Layout has 100mil cl for high voltage traces.

Yes, but there is simplier soft start circuit from B500 thread. Use zener diode instead resistor for sharp switch.
