That will be great Wiljj, I'll be able to fit a 5w in there vertically, no prob.
Maybe a hole for mounting post in centre of pcb, in between caps
Thanks so much
If you can manage to install 5W resistor in vertical then thats ok, i'll put a hole tonight in the center of PCB between caps.
Regards,

My AX-20 Build (3 pairs) using QQ12E5K1 pcb.
Hi-Fi sound, with softer treble than AX-14!
You can never get tired of listening music, even at a loud level!
Nice work,
Regards
ax 20
Greetings,,, what is its bias v?? and how dc max for 3 pair??

rail voltage +/-50v. i have not correctly measured bias. i tried to measure voltage accross one of the output resistor but got no reading. i think amp worked in class B.
AX14 will work with +/-56V DC rail voltage.
dear apex sir,
what is the measurement of this pcb?thanks
Many posts offtopic. Here is schematics again.
dear sir,
what is the dimension of this pcb.thanks
hi masood,
pcb size: 93mm x 60mm
regards
ur attached pcb is too big and not ax14

ok. thank you sir for the information. I also will try to make it,

AX-14 PCB Size: 60x82.5mm
I'd like to see the measument data, but I can not find it. Since this is an ultimate amplifier, I realy like to see what is the output spectrum look like.
You can check this post for a simulated result with comparison of Apex Ultimate and of other popular amps.
