Quoted from zacaj:I've actually used a Gottlieb (25V) chime box in a Bally EM and it works just fine, even though it seems like it shouldn't...
Yes, it works because the electrical pause is quick enough so the 50V doesn't do damage
to the 25V coils. Unless a playfield switch gets stuck, it'd probably stay okay..
To convert a 1 quarter per play to 2 quarters per play on a Bally Ball Bowler, I installed a 50V
step up coil on a 110V circuit. It worked, but you could really hear that plunger bottoming out, so
I spliced another empty 50V coil in the 50V step up's circuitry to act as a resister, and it cut it
down to 75V, which will be fine because the pause to it is very quick..
Not sure why Bally had to have a 110V coil for their Coin Relay, but it is..
