Pete,
My PRO headbox has 4 x very very small pre-drilled holes in the top of the headbox which ARE the exact screw positions for the tournament topper IF u want to add one.
Prince,
I had to wash the dishs today for the first time in 14 years, not because I have been playing the AC/DC pinball, but more like because I spent around$6300 (Pro plus shaker motor plus delivery) and the wife would have liked to buy a new car instead of "all these bloody pinball machines all over the bloody house routine". 
So I washed all the dishs to get in the good books (for 5 minutes anyway) 
Silverball,
That is not good about having 2 x machines in a row with issues. The chances of that happening must be 1 million to 1. I dont understand how those machines passed the quality control burn in tests which would normally pick up that stuff instantly. It would be good to hear later what you have found and any feedback would be appreciated by other AC/DC owners.
HAS ANYONE HEARD of anyone else having any issues ? 
mine seems ok, although at the very top of the playfield were it spells A X E the A bulb is blue and the X and E is white, i don't think they should be different, also there are 3 bulbs in a clear window just under the A X E one doesn't work, i had a look under the playfield, and there not bulbs there like litte electronic boards way over my head.
Mines the same in that clear window near the bumpers there's 3 flashers in the clear window now since the code update the top flasher of the 3 now doesn't work why? Also my apron flashers don't flash do anyone else's flash?
Peter
