My distributor has been terrific in sorting the situation but this product has been rushed through the door.
So far a LED control board and full motor/gearbox has been changed. A connector which appears to have black contacts on the cpu still may present a problem. Games appear to be working now although and LED tri colour has just shit itself. Other switch/wiring/adjustment problems were sorted out by myself with the distributors acknowledgement.
Owners take note....check the ball at the base of the bell as mine was loose and unscrewed itself before digging a trench in the playfield.
Nearly broke my backglass when lowering the backbox as the key can be removed from the lock in the open or closed position.
Using a USB to update the software that the machine doesnt like will erase all your memory and the game wont boot - this happened to me.

I would rather not comment on the other problems I have found in unboxing new machines. I like Sterns and have several models in my collection so understand that I am not being biased against.

Glad its working out Dave I also checked my bell and the ball is tight but will keep and eye on it..
