Yes, you can run the original amp from the -5 and +12 Volt PSU lines.
Simply connect the -5V to the GND connection on the amp and the +12V to the 17V or power connection on the amp.
It works because voltage is all about the "potential difference", that is the difference between the ground and voltage sources. By lowering the ground below 0V, you're increasing the potential difference of the positive voltage source. So the potential difference between -5V and +12V is 17V.
The only foreseeable problem with this is the need to isolate any grounded metal components on the amp from the rest of cabinet (ie: the heatsinks etc).

He he, yeah I think its a good deal if I do say so myself. Its going to be a 6 hour round trip to go and get it but it should be worth it. I should be able to get it up and running for less than £300 including everything. If it takes approx £5 a day I should get my money back in two months.
I thinking about doing some SF4 etc tournaments. £5 to enter, 16 players knock out. £40 for the winner, £20 for second and £10 for third or something like that.
@ KissMyWookie:
Thanks for the info. I think I'm just going to use the new amp in my cab. This new one doesn't have a I/O board at all so I'm going to transfer the metal frame to this new one for the AMP connectors.

personaly i would just give them a 3 button setup on plain cp,stick a 48 in 1 in there and leave them to it.its like opening your doors to complete strangers and letting them into your house when you trust them with an expensive arcade machine.
i would just use a generic jamma cab,there is no way i would let them at such a lovely specimen naomi.
on a side not i wanna a naomi.on ebay them too expensive,dont think you got that from ebay.but,its funny as my fbot was on ebay for £120 buy it now,man what a bargain that was so its just a case of watching and waiting,man trolling through 40 odd pages is pain in the ass.but,one day i will get a naomi or a proper candy cab.
and when you get her,take some pics and let us all see what shes like.

I'm going to go with the four button Neo Geo layout as it will be running Neo Geo games most of the time. Neo Geo games tend to display the controls too so it will be a good idea to have a matching control panel.
I also have a spare 2 player 6 button panel so I can swap that out for 360 tournys etc. Its all going to be wired with OEM AMP connectors to make it easy to swap over.
I did think about the multi Jamma boards but most of them are vertical games so wouldn't really be any good to me. I have just ordered a 100in1 MVS cart to 'evaluate'. I'm not sure what the legalities are of running something like that though.
The cab I'm getting isn't in quite as good condition as that picture but it should look nice with the new CP and marquee holder etc. I'm not going to go over board as it will probably get bashed around a bit. These cabs are great as you can disassemble them in small pieces to it will be easy to move about. I have a Jamma woody myself and they are freaking heavy and cumbersome in comparison.
I'm not too fussed if it does get knocked about as its cheap. Everywhere is non smoking nowadays so the most abuse its likely to get is a few knocks and maybe spilt drinks/student vomit :laugh:
I've ordered quite a few more bits for it this morning:
New Seimitsu PS 14-K buttons from Gremlin Solutions (red, blue, yellow and green for the action buttons, red for the start buttons and white for the game select)
Jamma edge connectors, PCB mounting feet and Jamma PSU from JapanDeal
LED striplights from ebay
9/12/15 pin male/female AMP connectors from Sega Shed
Excel credit board and C120 mech from giz10p.co.uk
I have decided to go with a electronic coin mech so that 10p-£1 can be inserted. I'll probably charge 30p for one credit, two for 50p and 5 for £1 (takes me back :)) At least then it won't all be 20p's to collect/change.
I am probably going to sell my 'SF4' Naomi if you are interested ;)
