most are made in China, so who knows what's really inside. Now SMPSU

Shame that--they could be profitably repaired.
Anyway, sorry for the topic drift. Good to see that someone else

I relish in 'repairing' these by slamming them into the concrete
lab floor, beating them into submission until I can get the case
to split.
Then I replace the fuse (if blown and so equipped), or replace
the rectifiers or filter cap, or whatever. Then I tape the
rascal back together. If the xfmr winding is open, out it
goes.
I probably should try to repair the ones that have switchers in
'em, but I have neither the time nor the expertise . . . (sigh).
