I need for my tests some good quality power supply. I have 12v 2amp, 3amp etc. and few boost converters.
I recently found my old ATX power supply , Odeyssey 400watt ATX power supply (dated OCT 2005).
I thought may be if I could repair it without much effort it is worth keeping as an additional power supply. ( I have plans to take 5-8 amps if possible to charge my SLA battery).
(images are attached below)
it is one with 2 x 13007 at the primary and one more (5vsb) installed on the same heat sink.
I took out the STD 13007 and checked it, seems okay. but I have an additional 13007 which when checked I saw DVM reading between Collector and emitter ( like what we get with TIP122 -Epitaxial Darlington). is it normal?
The third one in the row I think is burned (see pic) , I cant read the no on it. when tried with dvm , diode mode - no reading at all.
I tried online to find part and found this page
https://www.overclock.net/t/769505/linkworld-lpj2-430w-a-turd-that-thought-it-could-fly
the package and name is different but the inside is atleast 90% the same. it has a mention of C2057S transistor for 5Vsb. I searched online and found nothing. is it 2SC2057 ? I cant find that too. any idea about a possible replacement?
