I just received my parts-only PowerBook 520c from eBay. Confirmed with a multimeter that the problem is with the PSU - I opened it up and found the 3.15A fuse was blown, so I soldered in a replacement. When I plugged it in, it made an almighty pop/flash and took out some 16R and 8R2 resistors in the below image. The resistors are connected to the 'source' pin of a MOSFET, which I desoldered in order to test and it looks like it's not working properly.
I am interested in repairing this for the sake of having an authentic setup, but not sure it is worth it vs. getting a third party 16V PSU off eBay and splicing in the connector.
Is it worth buying a new MOSFET and seeing what happens?
Can failing caps cause the power supply to short out in the way it did?
