New to Pinball machines

[nrh_racing]

Hi
My first pinball machine is a Little Chief EM williams, i may of went into pinballs alittle to hard but i like a challenge, more rewarding if it works

Needs a bit of work but before i touch anything i'm want to work out a power source. It has the round 2 pin plug ( european i think?) and was told to use a 1000w step down, all the step downs i can find are 3 pin america versions.
It has probably been asked a million times but i did search and could not find anything, would rather get you guys opinion before i zap myself or blow something up.

Just a project for me and the kids, more me though 
Thanks I'm sure there will be more questions to come

Or is there a way to wire in the australia 3 plug straight to the transformer.

Think i was barking up the wrong tree, i was looking at this

Sorry if its a stupid question, still learning

  to the forum .
The 1st question is.. is the transformer a 110V or a 240V ??
Based on what you've said so far I am guessing it is a 110V in which case you would need to use a stepdown /

Thanks
It is a 15a-6771 williams transformer, are they 110v? It does look to be screwed to different holes so it may be different from original?

[nrh_racing]

Just seen on the schematic it uses that part number transformer, so looks to be 110v.
Am i correct to say that other plug is 110v outlet? Would that been used for maintenance people etc?

How many terminals are there on the bottom of the transformer?

[Boots]

Aren't most Eurpean countries 220-240V?

[nrh_racing]

2 down the bottom Black and purple wires, 4 hoops up top, 3 connected to wires. You can sort of see it in the bottom picture.
I think it is america 110v now because the power cord colours match to there power leads. For standard power cords in the USA:

BLACK = HOT
WHITE = NEUTRAL
GREEN = GROUND

I'm pretty sure the Williams ems can be converted I'll see if I can dig out a manual to confirm.

[nrh_racing]

Thanks mate, i will hold off buying one until i hear.

[ddstoys]

Sorry the manual I have only has 110v option.   Does anyone have a Williams em they can check ?

If its a US dometsic machine it may not be possible to configure the transformer to 240V. The mains plug will tell you if its an American machione or not.. they have a flat active and neutral with a round earth.. sometimes no earth at all.
What i can tell you with no doubt whatsoever is that a 1000W step down is WWAAAAAAYYY too big for one Em game.. i have a 500W here that i run 4 woodrails off.
A 200W is more than big enough and has plenty more to give.

jaycar sell 200W stepdowns if you want it immediately, but if you can wait, then Ebay is much cheaper.

The wound type ( true transformer) are better than the electronic type, a wound type really should never fail.

250W right here..

My 60's Williams Oh Boy had the same transformer listed (15A-6771) - It had a stepdown fitted.
These Auto Transformers were fitted to some European imports (refer pict) - But would not recommend them.


This is the stepdown I fitted to my SweetHearts

Would definately get the one Retropin recommends - Will buy this one next time I need one

Cant work out why they fitted transformers on the front end of playboard - Down right dangerous.

I dont mind the Powertech ones.. these are the Jaycar ones.. bit pricey but hardy too.
Mine are outisde the machines.. i change the plugs ( im running 4 woodrails) to standard 3 pin plugs( write 110V in marker pen on them) and plug into a standard multi socket  board. The conversion to US style plug is done on the input of the multi socket
