Ah, you have moved the NTC !!!!!!
Now I understand.
I do wish you would update your schematics when you change a design.

Schematic NE555 protect with NTC.

Protect without thermal and overload circuit.

ULTIMATE AMPLIFIER

Hi to all .
I have some question because i am confused.....Is ax11 and ax14 the some amplifier?
who owns the name ultimate amplifier?
I want to make an amplifier using 2sa1295 and 2sc3264 transistors
Can i do this with AX14?
Where can i find P.C.B in pdf format?
Thanks for all
Thimios.

They are diferent topologies and i recommend ax11 which you can find pdf in the last pages

No in the last pages you can find HX11 not AX11 .
HX11 is a mosfet autput amplifier class H.
I can't find AX11 and pcb ......can anyone help?
Thanks.

PRO input can be use with AX16, NX16, AX18, HV23... or you can add this circuit for over current detect to activate PRO input on NE555 protect.

ax11

yes,200W/4R with +/-50V PSU and single pair of MJ21193/94 as output transistors 🙂

the Dude nailed it! 🙂

any other change in VAS or INPUT?

Hi Mr Apex .
Finally this is HX11 as i can see.Is this recommended amplifier or AX11?

I hope that is a functional PCB without mistakes.
If anyone know please answer. In this case may be finalaize it tomorow.
Thanks to all.

I have use this PCB.

It works. See posts 2102 to 2110.

Good news!
Thanks for instant reply 🙂

Sorry, fotos.

Nice work .
My opinion is that MPSA13 must in thermal contact with main heatsink.
Any replacement for mpsa92? can't find it in my place..

AX11 under constraction

Here is more elegant version of previous pcb.

Hi Boris i like your PCB but i can't use because your PDF have gray collor on pads.As a mater of this low contrast and over etching.
Can you make something for this?

Ok. Therefore it is on the right place.
