Might be a dumbass question, but is that transformer just in there for the monitor?

My pfx is 240v so the 110v is spare .
Some of the Naomi use the doughnut transformer for sega audio amp .

some iso transformers like this one have it too .. so I’m using this for audio and 110v for if I need to add a sun psu.
Or 110v chassis in future.

I’m going to next try to run the capcom io & the Naomi sega io from the 12v & 5v rails on the pc psu so I can loose the Jamma psu.

And I have bolted the audio amp to the iso now it makes a good little shelf for the audio amp and has multi grounds points mounted there also .

Also, I like your style on utilising all of the PSU's outputs.
from the 12v & 5v rails on the pc psu
... plus, if you get enough information about the PSU itself you may find that there's a good few rails isolated for separate things which might give you cleaner power for each of them. :)

Didn't know that the JAMMA PSU was in there, too ... imma lean back and check the guts of mine now!

Great to see it fired up and working mate(y)
:):):):)
Thanks mate … yeh especially when you see the route I had to take
With it on an ancient sack truck! 😅

I would have done a 31khz & 15khz side by side comparison if I had another kettle lead at hand .. but that’s for another day 😄

Lol…. I have a access to a modern one with Hydrolic wheels but this old one is tall, Which actually helped with the awkward shape of the Naomi’s Big plastic rear cover. Now for the next one egret or centipede ? Not looking forward to it
