They are the 100/110/130 transformers you have there
You need to change your transformers or get a step-down transformer
B-19548: small 100/115/130 volt transformer.
C-19552: large 100/115/130 volt transformer.
B-19550: small 220/240 volt transformer.
C-19554: large 220/240 volt transformer.
B-19549: small German 220/240 volt transformer.
C-19553: large German 220/240 volt transformer.
Not correct Chris, you can wire the two transformers in series as he has done for 240 volt input. No need for a step down transformer.
+1, i have done this with my Roller Disco which has the American type 130v transformers in it. It had a GINORMOUS step-down transformer in it when i got it. I wanted to piss that off out of the game and wired the primaries of the two transformers in series as shown in Pauly540s pics.
It most certainly CAN be done BUT.. you DO get some flickering of the lamps as the coils fire, which doesn't bother me that much so i live with it. The voltages from the smaller transformer seem unaffected, as the game operates fine and hasn't missed a beat.. no resets or anything like that.
Also being a four flipper game it did weaken the flippers slightly which i remedied by adding a 3300uF capacitor across the bridge rectifier for the coils.. yeah i know its not a real good thing to do but it was justified in this case i thought
as the game plays the way it should having added the cap.
