PSU regulator will work, just use 6,8V zeners instead 12V, and you can set output voltage about +/-30V DC.
thanks.Can you design pcb for high quality amplifier for room like hifi sound using two 2sc5200 and two 2sa1943?I never seen your design using two 2sc5200.
waiting for the pcb pattern
apex, when will you release or show the pcb pattern for sr400?
or are you going to share it?
thanks
regards

I will share only DIY pcb version for this amps.
APEX Studio Reference SR400 is very expensive amplifier 🙄, and I share only simple schematic for DIY.

Thank You for this design, it's be very usefull for many diyers includeing me.
Do You use heatsinks to connect colectors of BC639/640, BD241/242 to GND?

Alex,
What software are you using? I like that mounting hole with a bunch of vias around it, it's cool!

PCB corrected....
Hi Mile ,
No, I have corrected, adding two jumpers on PCB . I intend to layout PCB for SR amplifier ....nice schematic . Thanks for sharing so many projects .

Thanks for this PCB, I don't think there is so many project, only reason is I don't have same topology for Hi-Fi, PA, Studio ...

when i change zener diode it work.now can i use 70volt ac and then can i variable until 50 or 40 volt dc?zener still can change or what?
to find high VA transformer is very difficult.at my town supply is 240v and i want to step down to 110V.then i can use 110v to your psu and then variable to low voltage.so i can get high va power supply.what u think?
step down is low price then toroid transformer
