As fairly new to this hobby other peoples experience is invaluable. There are a few tech tips on the tube, but in my opinion they are pretty random. I have found this you-tube series quite entertaining and always giving away a gem or two if you pay attention between the rambling & bashing, Rays Tech Tips. If you have not found this already I would give it a shot. It seems like the second round of Rays Tech Tips was launched today.
Just a Tip on the Tech Tip end of pinball
