I'd just try to find a smaller SMPS that will put out 5v and +/-12v that
will fit in the box of the original. ISTR that it is only good for 150
watts anyway. Hanging on a larger external PS would be rather tacky. I'd
look through Jameco or MPJones catalogs to find such a critter. Anything
that is original Amiga is far too much money for what you get.
Check the PS voltages first before comming yourself to major surgery. You
might just have a shorted bypass cap or something else easy to fix.
The 60Hz 'tick' was on the old CBM 8 bit machines. They had a seperate
10vAC input that was tapped for that, as well as provide 12 volts for the
analog circuitry. The A500 PS only provided DC voltages.
Drop me a line off-list if you need any help there.

An AMIGA A3000
needs some tender loving care, will not power up right
now.
No lights? No nothing? The A3000 PSU is not exactly the most
robust thing in the world. It's also small enough that a non-C=
replacement will be troublesome. I don't recall if that is one
of the models or not, but some C= PSUs provide 60Hz "tick" to
the CIAs (some, like the A500, do not).
