probably like you say an early polo without the psu cage,as for the lopti-fire it up and see what happens

try posting a photo as that may help a bit more,if we can't help here then the fellas at jamma+ will almost certainly know the problem
jamma+ has a good bunch of fellas that know their stuff on the older games

this tranformer should do the job,it should have enough guts to run a monitor

why can't you use the existing stepdown tranformers in your cabs,

1kva should run about 3 cabs in total

well a nice easy option would be to buy the drop in ac center and get this to run it all http://cgi.ebay.co.uk/TRANSFORMER-VOLTAGE-CONVERTER-UK-240v-to-US-110v-300W_W0QQitemZ320286000959QQcmdZViewItem?hash=item320286000959&_trkparms=72%3A1121%7C39%3A1%7C66%3A2%7C65%3A12%7C240%3A1318&_trksid=p3286.c0...

are you looking for the **** easy option or the cheaper option?

if you have problems getting one let me know as i have 1 spare you can have

there are many ways around this problem but you will need to do some wiring
the us iso transx are 120 to 120vac

nah thats no good,you 4R7(4.7) ohms 10WATTS-the one you have shown is 4k7(4700ohms)

J in electronics terms denote Joules which is energy
i don't think its that important in this instance,just make sure you get a 10watt 4r7

that system will not work for you as it based on the u.s 110vac
what you need is a stepdown transformer 220 to 120 ac
you can then take the degauss circuit from the primary 220 side and use the 120 side for the chassis

are you in the u.k,if so this will not give you what you need

it will work an absolute treat,this is a ready built system for lazy arcade peeps

i would not power the nanao with 135v,nanao are happy at 100v and will operate on 120v just fine
i reckon you would pushing it with 135v
that voltage is strange(135vac),is it marked at that or have you metered the output off load?

really could do with knowing the model/make of this monitor,as far as i am aware the monitors in these are vga only

yeah i bet the circuit board is cracked at that corner or the resistor has broken the solder pad from the track

r227 should be 4r7 10 watt,very rare for it to go faulty-i have seen the track crack around this resistor many times
check the track a meter the voltage on each side of the resistor,the side in line with c168 should be 145vdc
