My Project before go in to the box...
Thank's for Mile Slavkovic to share....
I've build many project of Your design but I'm forget to take a photo of them...
I don't want to comment about sound...I prefer to enjoy it.

AX14-S
Hi
I'm just finishing AX14-S, S for symmetric view
thanks Apex
but I just use one heat sink
I have a plan to cut it a little, on the center (only --- line on the image)
heat sink length is 30cm, 5mm thick
So which way is good for me,
leave it as single heat sink
cut it on ---line (leave only the finch side)
or cut into 2 pieces?
Regards

oh..., ok
it easier then
but
No sound, not connected to speaker yet
already tested with 10ohm resistor instead fuse (of course connected SGND+PGND) & the offset is small
about 4mV
I will add this AX14 with AX17 on a single power supply (300VA)
& maybe tomorrow I will have the result

AX-? 7 pair output
This is my 1st post here
I woud like to say thank you to sir Mile for sharing those amplifier design
I build your AX- 14 TEF with 7 pair output and +/- 75V rail and compare to my existing
Crown XLS clone same power supply same output board bias set at 50ma.
For me AX-14 TEF is the clear winner

AX14-S sound
then...
Now I know why apex suggest us to try this AX14
the sound is more warm,
more bass than AX17 maybe about 4dB , not sure but the bass I like
mid --- maybe not so far, just a little difference
high ---less high then AX17, but for me AX17 sound more clear
AX14 has some kind softness, I like it
that what I hear about those AX, hope my ears is normal
I will use AX14 for now & will make re-setting on AX17
so the offset can be low as AX14 which only -1.5mV & -2.5mV after warming
bias is about 100mA(when cold) & bias transistor work very nice too when it warm (not so hot, temperature when testing 26' C)
Thank you Mile
Warm Regards
I'm test with same input, same PSU, & same speakers
then...

This is very valuable for me,
Thank you
thats why I build powerful version of AX14Now I know why apex suggest us to try this AX14

and here is my next project HX???????
thats why I build powerful version of AX14
and here is my next project HX???????
HX1500
Hi remle114,thats why I build powerful version of AX14
and here is my next project HX???????
wow...
this is HX1500, would you share your experience too....
I will share AX that I built,
so here we go...
note: I'm use expressPCB to make .pcb file
I like simple software like that, works fine for me
just enjoy the process of making this amp.
Now I can start new project with better feeling
I hope this can be useful for others
Regards
