This is my version of the PSU , All tested all working no problems complete with PCB and BOM aslo with connection drawing, I mounted the transistors on a seperate PCB but you don't have to use the PCB you can just hard wire them.
Hi,
i've build this one from PicMaster, but on first attempt i got little firework with fog, both U1 and U2 are gone (cracked) :( does anyone have advice what can be wrong? i have C8 ~ 20000uF
could it be due to power transistors? (transformer, and 2n3055 's are the only parts which survived from my last attempts)
How can i troubleshoot it?
a) can i remove OPAMPS?
b) can i disconnect power transistors?
c) what else i can do?
