Those mosfet are absolutely oversized, the amplifier never uses all the current that are able to provide, it would be better to use cheapest mosfet, those are expensive.
Sorry guys and thank you for correcting my mistake....
really appreciated...

Could use transistors for audio in place of the MJE340 and 350 like 2sc4793 and 2SA1837 but with legs reversed, the mje have a very low ft, could be used also in place of the 15030 and 31 which are oversized and expensive and in this case the legs are right.
I'll never waste my time when i got chance to sit in my computer at home otherwise if my wife sit first i never get a chance... 😀

But anyways i cant wait to build ax11 quadraphonic,but i need a soldering iron and a drilling machine,and some solder,i aleardy have the components and one pcb.
What do you think of ax11,in terms of efficency and sound quality?

Whatever your expectations are from the AX11, this amp will make you very pleasantly surprised by the quality and power of sound.
Hello guys
I did the etching last night but have some problems with the brand of photo paper I use, I have some areas of the copper where the tuner didn't get well but I wan it to try again this board can still functional only one trace need to be fix for testing purpose I'm going to use this one, and I still have 3 more to go maybe if I change the photo paper brand I might get lucky, the fonts letters are to small so next time I will make them a bit larger so the AX-11 MKII will be more noticeable, I just want it to be honest I'm not so good at this thermal transfer, I might try later in the future photosensitive boards to see how they work, well here is my "almost alright board 🙄.
