Hello Alex,
Is it possible to desigh the pcb in such way that PSu, Protect, Soft Start, are all on same Amp Board, This will be very Easier and may use less Space. Right Now i have Put my SR200 Stereo pair in Chassis, There are lots of wires Running.

Hi alex, can you share your APEX collection.

C6 on AX17 is 1000uF, not 100uF (my mistake).

Excellent idea!

I like 🙂

PSU is to big for amp pcb, and there is same number of wires for DC or AC suply, but protect can be on same pcb with amp.

APEX D14

Sorry,I'm late to share it..

size is?

My new AX-14

Make 2 channel of AX-14 with 32 VAc.
Adjust bias 750mV on 10 resistor instead fuse.
Dc offset is -2,2 mVDC and another one is 1 mVDC.
Sound is better than my first AX-14 with bias 500mVDC.

Nice work, and what about amp VU ?

hi apex sir,
ax14 in progress, for home use.
is mje340,350 need small heat sink?

can u share ur vu meter pcb in pdf.
thanks
