I once took my ACDC Pro to a one day tournament. It ran non stop for a 8 hour period with the flippers and every other part on the machine copping an extra flogging.
I quickly cleaned the balls and gave the playfield a clean each hour. Nothing ever got hot and nothing ever played up.
The existing hardware works perfectly. Any improvements over this are a bonus. Prob got a whole years worth of my home playing in only one day. They are built well. Even in current form. Just some feedback.
Just don't hold the flippers too long then, you'll see!
