Well Joe and his tech Dom turned up. As they were testing the supercharger for speed, the gate snapped off altogether... Trying to get the supercharger gatepost off without taking the playfield was pretty damn difficult, but in the end succeeded, riveted it back on and got it back in. Marty, do you have some trick to get it off? They had a bugger of a time with it, mainly trying to undo the back grub screw (there's 2 of them) that hold the gatepost on.
Anyway, gate back on, and aligned properly and did a test. Definitely went faster, but still not quick enough. Dom wasn't happy so did further investigation and found that one of the magnets/coils wasn't working. After much tests with a multi, found out that a tip36 on the circuit board was stuffed, replaced that, retested, and voila, the supercharger is going like a bloody demon now. That coil must have been out the whole time since I bought it as its never been this quick, absolutely flies now...!
They fixed up a few other minor issues as well, and they are also looking into my multiball release post. I found out that the multiball is supposed to be released slowly one after another, not ALL at the same time. Apparently the post is binding on the way up, so once it goes down to release 1, it cant get back up quick enough before they're all gone. Anyone else experienced this?
