Unknown Macintosh SE Power Supply

[jasonfortheworld]

I picked up a bunch of SE machines recently and I'm going through the process of recapping everything in them, but I stumbled across a power supply that I don't recognize at all. It's not branded in any way, and lacks the "Made in Singapore" tag that the Hitachi supplies have.

Most interestingly it has an internal switch for picking 115v and 230v, but was manufactured in the USA. And it seems to be hand soldered based on how the PCB looks.

Has anyone else come across this power supply before? I'm wondering if it was some kind of low volume replacement part that was used in the US. I picked up the computer in the Los Angeles area with 4 others that all came from a grade school, so I'm guessing it's not some international machine.

3rd party replacement. I’m pretty sure the stock power supplies are auto ranging so a switch like that is a dead giveaway.

check a repair book from around 1990, might be able to find the company that way.

Agreed; this is pretty definitely a third-party replacement.

Looks like someone else ran into one a while back...

Super interesting! Thanks for sharing the thread. I must have missed it when searching. I wonder if it's worth recapping and documenting for the future, or if I should just swap it for a new power supply.
