Cant find anything on the monitor to see what it is... But wanna kno if the monitor used an isolator? It has that big sliver box on the floor ..... I kno it's a power supply but is it also an ISO?.... Thanks
 
if you don't see the big block with copper windings then no, it's not an isolation transformer. as an example, Midway switched to something similar in the mid-90s and very frequently people install monitors that require isolation transformers (like the WG K7000) and they typically come here saying "my monitor got blown up" or something similar cause it's not an iso, it's just an AC distributor.

I'm fairly certain those cabinets shipped with Wells-Gardner U2000s from the factory, since they were standard resolution games. the U2000 does not require an isolation transformer, which more than likely points to you not having one in that cab.

going with my Midway story, that's because Wells-Gardner started making monitors that had their own switching mode power supplies on-board and thus eliminated the need for isos, and the manufacturers followed suit. Sega wound up doing the same I guess.
 
I've worked on a few of these machines and they had WG U2000 monitors without a cabinet isolation transformer. The big box you are referring to is the power supply.
 
Thanks guys... Getting ready to move a new monitor that needs an ISO ... Don't wanna be that guy who says ( my monitor just blew...) lol
 
Original dedicated duramold? Mine has a K7400 which doesn't need an iso. My cabinet doesn't have an iso either.
