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

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.
