Good news - mine worked so fingers crossed for yours

functioning PSU again though I've not tried it back in the chassis yet...
Nice! My replacements arrived today and unfortunately I did not have
such good luck. No smoke or fire, but now I get nothing at all out of
the supply. The whine is gone, but there's nothing output at all. The
fuse/resistor didn't blow (it's still got continuity across it) and the
transistor I replaced is still fine, but there must be something else in
the supply that's causing issues...
Blargh. I hate working on power supplies.

are education-only suppliers but the same part numbers work with
Farnell/Element14. Part# is 1692450.
Thanks! Yes, that looks very similar except mine has a tolerance rating
of 10%. Vincent helpfully pointed me at:

which look like they should do the job, and I ordered a handful just in
case I ever need a few more.
