And then that R3, won´t be better to split it in two emitter resistors for the LTP? Look, I am sure 100% you design is OK, I am only trying to understand a little bit how it works.
Thanks- ATX

Yes AX-14 can drive PA speakers, but sound quality will be better with Hi-Fi speakers,

Looking forward to build ax14,I want to build a stereo set.
I am having a pair of 2ski530-2sj201,2 pairs
2sc2922-2sa1216-2 pairs
mjl21193-21194-5 pairs
can you suggest if i can use these for ax14, And what would be the optimum voltage to be used.
Also if i use higher voltages than recommended what precautions should i take-will bigger heat sink be a good option

what would this amp be class -A or Class-B

Also i want suggestions as how to get 300 watts rms with this amp.
I need to for tower speaker which have 2, 8inchers in 1 tower and rated at 200 watts rms at 8 ohms per woofer, so 2 woofers mean 400 watss rms

i used to diy a long back, its been several years, so i would need your guidance.
VAS from AX-14 can work with +/-120V DC rail voltage without change, with output stage upgrade U can get 500W/8R. I also use MOSFETs for some versions...
I made this class H version ' Ultimate 500' for test, and work great with +/-120V,+/-60V,0V rail votages.
Regards

Sound of AX14 is very good, bass are impressive, trebble and médium not agressive.very dynamic. (very much power for so a little board at 40VDC)
I'll made a complete amp. I've print a second regulated psu board and the second amp board.
It will be 2Xmono: 2XTransfo 30VAC 120VA (have them on stock), 2 reg PSU with 4X4700uf (find nichicon 4700uF/80V for 2Euros/p).
I think i'll be very happy with it.
Thanks for protection board, but i use velleman K4700 (very little board for two channels protection).
Thanks again, will give some news about the stéréo AX14.
I want more diyers like 'jeff9200' to share expirience with AX-14, PCB size is little but this is great amp evan with single pair of outputs.

Compare AX-14 with 'Goldmund clone' on 'blind' test will be very interesting, considering the price

I suggest U to build AX-14, it's 'The Best DIY Amp Ever'. If you realy want to build diy amp no need to planing, colecting schematics and parts... and wait a year or two, like most diyers on this forum, AX-14 U can build for fun over the weekend and enjoy... 100W is more than enough for home listening.
Regards
