    scf 4242 7jt Replacement

    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.

    PS: If anyone can give me clues to troubleshoot I will be very gratefull
    This psu it is REALLY very important to me. If someone can sell me an old AT PSU with 300W I will be very gratefull also
    Many thanks for your kind help,
    Jorge

      Unknown transformer : how to find a good replacement part ?
      by the_rem
      Hello guys,

      I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

      I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

      OLD Socket 478 custom bracket + NEW generic cooler
      by BleedCap
      I already posted this on vogons.
      Its a 3d printed custom bracket for socket 478.
      I used this AM4 bracket as a base design.
      Its to be use with cheap generic clip based cpu cooler.

      Reason for doing this is:
      - Its hard to get/find a good copper base cooler. Even if you find one, the price is ....
      - New generic cooler is cheaper and can use bigger fan (less noise)

      I tested the bracket with cheap chinese horizontal cooler + fan taken from CM hyper 212 evo.
      The processor that I was using is P4 2.4Ghz prescott....

      PS4 controller left stick potentiometer replacement issue
      by ezenia
      Hello,

      Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

      So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

      I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

      Macbook pro logic board replacement parts quesion
      by boosti45
      i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...

      klipsch kda-500 amplifier suitable power supply capacitor replacement ?
      by r2digital
      I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...
