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.
