Well you've identified it.  It's an old style power supply out of a 19" upright GK cabinet.  They are difficult to find, and if you do find one it probably doesn't have much life left in it either unless you recap it.  It can be made to work with the much more plentiful S2000/I-game power supplies by repinning the AC input on the power connector.  Then all you have to do if figure out how to mount it in the cabinet.  On my old 13" cabinet I took the guts out of a S2000 power supply and transplanted it into the outer case of the original power supply.  Only one or two of the screws matched, but I used zip ties, bailing wire or something to keep it held in place.  Been working just fine for years now.

Wow...that was made in the 29th week of 1997...about 26 yeas ago!
You think it's old enuff?
I think that puppy's had it! 


Time for a new one or use the guts of a S2000 Win Tact PS or something like that.
Those run for about $50 on ebay right now shipping outta New Jersey.
Talk to the seller...see if you can get his $35 shipping costs down a bit?...>>>

That's really the way to do it in my opinion.  If you ever need to replace the power supply again it will be much easier to do.

I have the same power supply and cannot find where to buy these old caps to replace.  Anyone know where I can buy them?  I have all of the values from the PS power supply topic post from Tom.  Or if someone is selling one of these newer power supplies.  I think the Win_Tact WP203p11 and I will repin.
