I am suprised at you! The 'AC power supply' is really simple inside,
there are no custom parts (in fact the only 'chips' are optoisolated).
There are about 10 discrete transistors on the protection board, that's all.
In other words, this is something you darn well should be repairing, not
replacing.
Ditto for the fuser itself. The lamp (if that's what you need) is cheaper
than the complete assembly. And it doesn't take long to fit it.

Thanks, it helps in that it tells me where the
problem may be...power

would be about $30-$70 for a replacement part, which is not that hard
to replace yourself if you can work a screwdriver. Webby URLs to
