Are you looking to use it or is it important from a collector's perspective to get an original?
It's not a super common machine, you may need to purchase another system just to get the psu...
I saw some web shop selling new ones but I'm guessing you don't want to pay too much for one? Can't find it now - it was some time ago...
How about putting a new transformer in the brick (is it the small or the large one?) - are you comfortable with that?
You could run it off DC as well, there are rectifiers in the console and then capacitor with regulator(s).
10VDC on the 5V line and 17V on the 12V line should be good enough with some margin - you could use a higher voltage, like a 19V laptop PSU but the regulators will run hotter - the 5V will be hottest as it has more energy to dissipate.
Those two DC values will keep the regulator cooler than the originals though.
The Luxor version runs 9VAC and 15VAC, these have top voltage at about 12.7 and 21V - with the large capacitors the voltage will be held pretty near those values - so they run pretty hot on the original supply.
I guess there's some margin for power fluctuations on the main grid.
Feeding 5V and 12V directly to the circuitry inside is another possibility.
You only need about 0.2A 15VAC and 1.5A 9VAC.
But something LIKE this would work:
