Scoping tbings in there would sure be informative.
The prolem is that if this is like most small SMPSUs, then almost all t= 'interesting' circuitry (oscillator, etc)
is on the mains side of the
isolation barrier. And therefore you can't just connect a 'scope to it,
not unless you like shorting out the mains via one of the rectifier
diodes and the earth (ground) lead of the 'scope.
This is true, though at the time I wrote that I was thinking about scopi=
ng=20
the outputs.
