Quoted from classicgamefan:Frequent airballs from right ramp.
This has me concerned the most. The right ramp seems to have a 'bubble' or warp. I wonder if it got too hot at one point. Unfortunately, replacements for this ramp do not appear to be available. It works properly on weak shots. Does anyone else have this problem?
I found one at Pinball Spare Parts Australia: http://www.pinballspareparts.com.au/
It was pricey, but it was the only place I could find one.
