give the right RMS output. These are fine for running you travelling
clothes iron or other heating device, but are no good for electronic
stuff. In fact they will do a lot of damage (the peak voltage applied to
the laod is still 230V). I had to rebuild a Mac+ analogue board that had
suffeerd from one of these -- suffice it to say I had to replace most of
the trnasistors and capacitors in the mains side of the PSU.
Of course, I meant this one, not the first one!
