Joining this club as my restoration is nearly complete. I will post the pics I take during my unveiling party tomorrow! Picked it up as a beat up garage piece of junk find and poured effort into it until it shined like new!

Re: recent sound conversation
My game also has Proto 2 sound chips, but I do not have a female voice in my game AND my main gameplay theme is different than the normal song. I posted a video of the alternate (Beta) song here:

I also have a virtual pinball cabinet I built, so I grabbed all the roms from IPDB and tried each one until I eventually found the European Prototype 1 rom which has the same sound my machine has. including no female voice, and the alternate music. I have since bought a chip programmer, and some blank eproms will arrive tomorrow (didn't want to ruin my only working chips in case I screw it up).

All done!

Can anyone tell me what this part is?

Ahhh excellent thank you. Which way should it be oriented?

Yea no damage there. You said you swapped the sound roms. Did you also update your game roms? If you run new sound roms with old cpu roms you might get issues. LA-2 I believe is the cpu rom version you want (assuming the sound roms you used were the latest LA-3)

Sometimes my pit launcher isn't strong enough to get the ball all the way over to the flipper and it rolls back down into the pit. This causes the magnet to time out and you miss it. Anyone know how to strengthen it? Do I need to replace the coil?

It has a new coil sleeve. I'll check the alignment. Can someone take a top-down picture of how the wire ramp is supposed to line up? The screw legs on mine were broken when I got it and they were rewelded. That might be off.

Thanks for the pics. Mine appears to be properly centered. The ball goes up into the wire-form and gets about half way to the flipper near where the wire-form bends a bit before running out of momentum and rolling backwards and falling back down. It doesn't appear to be hitting the wires on the way up. Maybe redoing the solder on the wires to the coil will help with the inconsistent strength.

Just following up, I redid the solder on the coil for the pit. The ball now sails easily to the end of the ramp and the flipper. The wires and solder did not appear damaged, but it definitely fixed it. Game is now 50% less frustrating. No more timing out sudden death waiting for 6 attempts to pop the ball over.

Failing all those useful tips above, you may have a switch matrix issue with lock 1 and shooter lane switches (and possibly a third switch you haven't even noticed anything wrong with.) I haven't looked at the matrix diagram to see how closely related they are, but its worth looking into.

Always sad to see them go. No longer a member of this club. Fortunately you won't get a more enthusiastic member than HotPieceOfSass

How did I never think of a live alligator topper...makes just as much sense as the ones on the show

Yeeeeeeeeessssss

Replace these with the latest or you likely won't have all the correct sounds.

I had this problem. Resoldering the coil lugs fixed it. They looked fine beforehand, but it worked.
