Quoted from markp99:Fully agree. My JP is tuned to perfection, love working this and GoT as much as playing them. Tweaking is not a problem. My comment was more related to restoring an older machine - playfield, cabinet, paint, etc. I just do not have space for anything more than lifting the playfield.
It's not that hard to make a 20 yr old machine play like it's brand new. In fact, it's quite easy.
