Quoted from EMsInKC:Williams games with DC bumpers were so much faster and livelier than Gottlieb games. Even Ballys with AC bumpers, but 50 volts powering them, are faster.
Agreed, have played my Gottlieb King kool a lot since finishing up the resto....
Then hopped onto my Williams Aztec... holy crap! I forgot how fast those DC pop bumpers were....
