Multicade AC Wiring

[mutate]

Hi,
I'm thinking about turning my Dig Dug cabinet into a Multicade.

My first step would be to build a working power supply. I've seen these two guides but still have a few questions I'm hoping someone here can help.

I'm no electrical expert but it seems like there are two ways I can go.

One would be to follow these guides.

Two would be to skip the "AC Fuse/Holder, AC Line Filter and AC On/Off Switch" and use a Power Switch with Built-in EMI Filter and Fuse Protection like this one:

The second option seems more streamlined. Any recommendations on which way to go?

Also if I go the first route can anyone shed some light on fuse amps and ac line filter amps? I think the ones from Bob Roberts are 3 amp fuse, 6 amp ac line filter? I don't understand electrical so I'd like to know why you would use those two inline?

I'm new to the hobby but very excited to get this build underway!

the power bar is your friend. it can easily be wired into the cabinet and provides a safe place to plug stuff in.

you can do all sorts of fancy IEC connections and whatnot, but really, you aren't going to see it much.

be sure to take a look at your monitor and see if you need to run it from an isolation transformer or not.

Oh sorry, maybe I wasn't clear.

This is going to be a Jamma wired, 60 in 1 or 412 in 1 game. I'm converting a working Dig Dug (sorry if this offends any hardcore purists). I'll have to open it up and see what type of Monitor is in but I'm guessing it is the original. The only modification to it is a free play button on the coin door. The power brick is the atari brick with big blue.

Maybe I can just run ac off of this to a Switching Power Supply to power the multi PCB?

Your handle is very fitting.

you'd be best to switch that whole power supply out for one of these types:

it will be less hassle and more reliable in the long run rather than trying to reuse the original power supply.

a multi-in-1 board often has a molex power plug (same as the computer harddrive or cdrom drive connector) on it. you can jumpstart a standard ATX computer power supply and power it this way too.

I think I'm going to just tap an ATX power supply into the marquee light like this.

Simple and clean, plus I can leave the old power supply to power the monitor.
