PCBWay says the "author will not allow download of gerbers" and when I "add to cart" it loads a 6.7mm x 12.8mm board - can't be correct size??

Use protection out from AX22 and use DC555S protect...

ty for answer mr mile. you mean like this?
but for protection i cannot use pa protec? i was like it for 15v for xlr circuit and thermal protection too. and i want to use regulated amp psu one of yours is that all can be use together? sory for many questions and for my bad english. thank you
ah i forget my transformer giving me 2x50vdc and 2x20vdc. i rewind secondary. thank you again for all your help.

Re drawing pcb for protec. tomorrow i can finish and start pcb ty mr. mile
Attachments
i start for ax14 man ty just there is that cap is different on pcb and on schematic. i dont know which one is right. i made before this ax14 its not work i throw away cause thin lines and repair make them trash. so i making again now but i will draw new pcb with protection.
so i need to know which polarity is right. on schematic or on pcb.

I think the schematic is correct but I believe C6 polarity does not matter. C6 could be non-polar electrolytic but you can use an inexpensive polar electrolytic because it has very little load. Anyone please correct me if I am wrong.
Ty for answers i chech some pics from who make this amp. All use polarity from pcb. Ty for answers
i finish redrawing. pls have a look. i take out line under the R24 for protec. this can make a problem on it voice? or any desing faults if you see pls write here so i can learn more. thank you for all helps.
i will make it next week so i am just waiting for your answers...
i will put here gerber files and all i have after see its work. ty..

Hello Mr. Mile, can u please update TP2 with TP3 (bass, mid and treble).

hi mr mile pls can you just look a little to that pcb i trying to make, maybe you can see some mistakes. thank you .

and you said different voltages abouth it.
some where you write "Circuit was tested on +/-90V rail voltage,
but with single pair 2SC5200/2SA1943 +/-56V is maximum."
and another page you write "I suggest rail voltage +/-45V for single pair".
i need rewind transformer cause i read wrong too and make it 50-0-50vac before. now i opening again going to make it 40-0-40Vac. is this too much for ax14?

I already have TB3, but I think TB3 is only tone control with buffer(if I m right). TP2 is Preamp with tone control, but there are 2 band (bass & treble). If 3rd band ( mid) add in this Preamp that's awesome.

I think that is too much for a single pair. You can get by with that for 8ohm only but you will need good heatsinking. I doubt you would notice any benefit from the higher voltage.
ty for answer my friend. i just trying make what is suggested. some times i misunderstand cause of my bad english and making mistakes.
what you suggest for transformer for single pair.
