Hi guys, I have an old AT PSU PRO-POWER Model PPS-250 (very usefull to power my muscled commodore amiga 1200) It needs a good 5V spply... Cheap PSU "500W" dont have muscle to power up my baby). When adidng a dummy load with an ceramic resistor I toutched with my alluminium cooler in another alluminium cooler with an SR1040 and 2 rectifier diodes. some sparks came out and my psu never turned on again . I think that I have one of the SCF 4242 7JT dammaged. Can any one tell me a good replacement?? I has an alluminium cooler with 2 scf 4242 7jt attached.
Hi to all! My name is Jorge, I am with almost 42 years old. I am from Portugal. My goal here is to learn how to repair old AT PSU that I messed up when shorted a ceramic resistor with some aluminum cooler
