Very nice build hassan. Very very compact and symmetric looking pcb too.
Congrats!.
I am planning to make it with single pair version , I have posted the design somewhere in recent pages, which will be diy friendly, though I am planning to manufacture them in 2.4 mm , 70um copper. However due to lockdown, its on hold.

tnx mr prasi...i see your pcb too....your pcb is very nice too...
i made apex ax17 with to3 and bjt...full symetricall and very very compact.
ax17 with to3- 2pair
with permission from mr mile slavcovik:
apex ax17 with to3 transistor in
Running out
high compact in one layer
mr mile whats maximum voltage for 2 pair mj15024/mj15025?
and about 2 pair MJ2955/2N3055?
i use TO3 pack for To create a nostalgic state.

I’ve got one FH9 channel powered up and singing away 🙂
Currently using a linear psu feeding 43vdc @ 90mA bias. DC offset, although not adjustable, is more than acceptable at 10-12mV. I’m recycling an old amplifier chassis, therefore the odd device mounting is because I am utilizing the existing tapped holes 😉
Easy peasy build and really sounds pretty darn good with nice bass weight. Looking forward to getting the second channel fired up to get the full FH9 demo.

Nice work Vunce! Can’t wait to hear your listening impressions after you go stereo. Wondering how this little amp stacks up to your other Class AB reference standard amps.
