Hi guys,

Been a lurker for a bit and am now working on a cocktail system where I'm having some issues figuring out what I've got.

I have a Phillips tube and a Wells Gardner chassis. I can't tell much about the WG chassis though. I think it's a 7100 or 7200? Maybe you guys can steer me in the right direction. It looks to have the power supply built into the board so I'm thinking I don't need an isolation transformer?

Also, my main reasons for figuring out what the chassis is, is because I don't understand/know what the connections are to the chassis. It looks to be a 9-pin connection for RGB, Sync, etc and a 3-prong power connection. Is that all that's usually needed on this board?

I'm not totally clear on the 9-pin connections for the board either. Do they all have to be used? My Jamma cable only has 5 pins from my recollection.

Here are some pics in the meantime. Thanks for any and all help!

Image Descriptions:
-Full chassis board
-Image diagram of chassis that was pasted to the monitor supports
-One end of a cable (power cable?) that comes off of the chassis board
-A loose cable that I found inside the arcade cabinet - no idea what it's for?
-Chassis and serial number sticker

Thanks for the help! I've checked that site out as well as another one to help identify it but the pictures are so small. What are key identifiers? It looks kind of like the K7000 but the game that was in the machine has been upgraded and the isolation transformer was just sitting at the bottom of the unit with no connections. Also, the far left of the chassis looks like an on-board power supply, or is that not?

I read in another post that I could probably get away with just hooking up 5 of the 9 connections on the chassis (for the monitor connections). Is that correct?
 
That is definitely a K7000 chassis.
The two pin connector in your hand is the AC power which MUST be from an isolation transformer.
The JAMMA harness has 5 wires.....Red, Green, Blue, Ground, and Sync....that is all you need for most games. (composite sync setup) Your sync wire will connect to the -H Sync pin on the chassis.

I can't quite tell what that pic is showing with three pin connector and power cord. So make sure that verify there is an isolation transformer in there and wire that up for power to the monitor.
 
Thank you guys so much for the help! I don't have any other chassis' to go from (or have even seen one before) so other than trying to match it up with pictures on other sites, it's very difficult.

Now I have a new set of questions for you! haha :p Now that I need an isolation transformer, I need to know if either of these are any good. I'm going to attach pictures of two units that I found in the machine. One was hooked up and the other was just sitting there.

The "newer" one, is just an AC cord with what looks like an isolation transformer and then an output three-prong jack. Is that an isolation transformer? The other one looks like an isolation transformer (from what I've seen) but has so many different connections on it. There's an extremely faded label that has various inputs (and maybe outputs) such as 115v, 0v, (what looks like) 185v, and 12v. Maybe it was an early switching power supply or an isolation transformer that can work on different voltages?

Last thing is - should I even use either of these? Maybe I'll just buy a new one so I know what I'm doing but where abouts would I find one locally (shipping would kill me on one of these)? I'm thinking a tv repair place might be able to get these (or have some)?

Thanks again for the help! PS - went to the 1st annual Pinball and Game show today here in Ottawa. Was quite the show and was impressed with the wide variety of games and enthusiasts that showed up! I think a guy from another board is going to post pics. I'll link to them when I figure out where ;)

The black one labeled "Frost" is the isolation transformer. Inputs about 115VAC and Outputs 115VAC. You could probably still use it, these things are pretty durable because their just big coils of copper. If you want to test it just grab a multi meter, plug it in, and then measure the output in voltage in AC and see if its in range. Anything between 115-125ish should be just fine.

On a side note the other transformer is probably used as a linear power supply for older cabinets, you won't need it if you plan to throw in a switching power supply. JAMMA games simply need +5v +12v (occasionally -5v) in DC so it's simple to use either a switching arcade power supply or a standard ATX computer power supply.
 
Thanks so much for the help! I will wire it up and let you guys know how it goes. Couldn't do it without all of the help :)
