comment stands. I don't think I'd consider it any more work to replace
WW ones and re-wrap them than if they were soldered onto a PCB
(especially if it has multiple layers), as long as you have some sort
of schematice/wire list. If you wanted to be creative, you could
probably cut the pins off the old sockets (or disassemble the sockets
to get the pins out), and figure out how to replace the sockets
(soldering new ones onto the old pins) without having to re-wrap
everything.

This machine is wire wrapped. Replacing the sockets would be
tantamount to building the boards from scratch. good contact... this is going to be an ordeal :).
The sockets
themselves are going to be a problem -- they have gold contacts (I
_think_) but the actual socket doesn't expose any accessible metal
surface -- the pins go through a hole (that's just barely larger
than a pin) in the plastic sheath and beneath that are the
contacts.
It sounds like the sockets you have are of the style that never
really worked well. You may want to consider removing and
replacing all of the sockets, if you want the machine to work
reliably, either with turned-pin (machined) sockets, or cheap
"wiper" blade sockets, both of which are more reliable than what
you have.
