i saw an old thread about a grundig-beko psu. i have a similar psu in my hands. the 12V is ok, but the 24 not. the main transistor is gone (literally exploded) with the ic circuit and some other components (i found an opened diode and a resistor). i read in your post that the main ic is an Infineon ICE1QS01. but i wanted to know, if possible, what is the main transistor? from my experience it might be a 11N50C.
i want to know too if you are interested in selling that board in case im unlucky repairing mine. thank you.
