Drat... what is wrong with me? :)
The fellow is located on the PSU / Printer board - there are three
transformers on there; it looks like the two larger ones are
identical. It's one of the two larger ones - it seems as if the two
giant screw-on caps on that board were shorted... they're going to be
replaced. Can probably rewind the transformer if I can't find
something suitable, just am feeling a bit lazy. :)
Thanks for the kind reply, Tony!
