all better characteristics of to3 transistors are transfered to an amplifier it self,the basic pcb is from alex mm,his version 3.1.

What is the recommended TO-3 output transistors? good layout by the way .

 

[44250]

that is to be gratefull to alex mm and d.veljko!

recommended would be bipolar transistors with same or higher voltage,power and hFE. i believe that Mile-APEX could give a more specific list of transistors,i don´t have that experience to do so...

Thank you so much Mr. Mile Slavkovic...very good design you have...I still need your advice...
Best Regards

I would like to have information on this PCB:
APEX B500
Not if you will have in pdf side copper components, the diagram, pcb size

I'll Share with you, you must give in order to relay protector speaker module can work as protect.

I suggest set bias to 20-30mA per pair (600-900mV at 10R instead fuse). With 50mA per pair you have over 20W disipation per channel it's too high for your small heatsinks.

sir Damanhuri
nice PCB ,what is the out put power in (8ohm,4 ohm, if it can drive in 2ohm) this you'r new B50 pcb layout with 9 pair power transistor & what is the +/- DC v

thanks
