What do *you* do when a power socket on an electronic device develops a fault?
Mhm of course you rip it out, remove the plug, solder the wires onto the board (never mind that you now have a 1kg power block hanging off the 1kg computer; that's manageable), and secure them in the hole with #BluTak. It's the perfect strain relief, right?

Mmm I think I found the fault.
Somewhere in this optical mess of solder and wires there are three open solder joints. That may have been an effect of the lack of strain relief, or it may have just been like that.

Anyway it cleaned up. Some of the original copper had lifted when the socket was taken out.
This was a PCB-mounted 13-pin DIN socket. Why anyone would specify a 13-pin socket for ... +12, -12, +5, ground and two sides of a standby switch ... is not obvious. Maybe this allows the higher-current connections to come through multiple wires (up to 4). But these were used for power in various products in the 1980s.

Socket installed. Not the tidiest of jobs, and it took some finagling to bridge the trace cracks and still keep the rails separate.
(I then put some solder mask over the bare copper and left it in the sun to cure, and reassembled the thing, forgetting to take more photos. But that was the bit I was here to complain about.)
@electropict I think it says a lot about me (and my one eye) that, before I clicked to see what the picture was and finished reading your post, I thought you were referring to an eye socket.
"Ooooh, that's a new type of eye. Wonder what it does."
