Eight Ball Deluxe 120v to 240 volt conversion

[danmcmanus]

  We just moved from the States and brought our Eight Ball Deluxe table along.

We are trying to figure out how to convert the transformer from 120v to 240v.

We've been told it can be done, internally, but we need help with the correct procedure.

We don't want to blow our baby up! 

Is there someone who can help us with our situation?

Thanks

I'll see if I can get to my machine and have a look at the configuration.

According to the power supply schematic from IPDB - http://www.ipdb.org/files/762/Bally_1981_Eight_Ball_Deluxe_Manual.pdf

If the machine is set to 120 V, the transformer jumpers are set to ;

Pin 2-8
Pin 4-6
Pin 7-11

(There will be two jumpers 5-6 & 6-7 already there)

For 240 V you will need to change the transformer jumpers to the following ;

Remove Pin 2-8
Remove Pin 4-6
Add Pin 4-8
Leave Pin 7-11 (if already set to 120 V)

(There will be two jumpers 5-6 & 6-7 already there)

Please be sure you know how to read the transformer pins. They should be already clearly marked. The schematic I'm reading from is on page 50 of the link I've provided. Double check your work.

Check the value of the Varistor (on the filter located in the cabinet) - it should be rated to 250 VAC. You will have to change it IF it is rated to 120 V.

Hi there

Another alternative to get it up and running short term or long if you don't want to play with wires is that you can purchase a transformer 120v to 240v, and check the schematic for peak amps in the ball park of 140amps but this is based on my Surf Champ. Jaycar Electronics sells these for about $125.

US plug in one end and then Aus 240V out the other end.

Yes - you can use a step down transformer if you don't want to mess with the game transformer.

You should be able to find a cheaper one on eBay as well.  I am using a step down transformer on my Hulk machine and haven't had any issues with it.  From memory mine cost about $60-70 from a seller that is in the Heathcote NSW area.
