Use wire jumper instead this line, and all MJEs must have heatsink (Arif SR200 also)

No changes on protect, just add overload detect circuit from B500 if you need.

Ok, thanks apex ...
1 jumper I mean is this wire jumper, sorry for wrong drawing
& this MJE on center also need heatsink right, same heatsink as the other or smaller heatsink will be okay?
I guess I need to move it a little if need same heatsink

@ Arif Budiyanto, maybe you mean this type of SanKen

Hi Apex,

Im new here, almost read this thread from the beggining. It is so exiting to hear this stuff with my own work in the future.

I have here home made transfomer 800va but secondary output is quitly different 60 0 57 vac. After rectify by bridge diode it become +83.2 and -81.5 vdc.

Can this affect to supply class a/b amplifier? or is their other way to fix output dc to get balance?

DIY expert are welcome to reply.
