Is there supposed to be a post sleeve installed at the tip of the left-hand inline/outlane ball guide? If so, what diameter sleeve? There is on mine, but for some reason, the sleeve appears to be too big and when the ball starts down the left outlane, it gets stuck between the sleeve and side of the machine since there isn't enough space for it to pass. Could just be my sleeve is swollen and I need a new one. Or it could be the previous owner just put one in to make the game easier......

Anyone have any thoughts and if possible, could someone post a picture of what this area should look like?

That's what I suspected. Probably installed as a hack to increase ball time. Nothing like a previous owner just putting a screw straight into the playfield.....sigh.

How does this affect the operation of the mini-playfield? I ask because I have yet to take apart my mini playfield for replacement (already have a new mini-playfield and the cliffys for it, just haven't gotten around to it yet) but when mine raises, it settles crooked, with the right side being a little lower than the left. Not low enough to affect game play, but this has me wondering if a missing or damaged roller could be the issue I might want to look for when I do take it apart....

I have the same alternate translite. Absolutely love it and it really adds to the visual appeal of the machine. People complain about the light show when the translite isn't the original, but I find that it actually looks really good with this particular one.

Don't the doctors light up appropriately on the speaker panel anyway? That solves that particular problem for me.....

Since I'm basically stuck in the house for the foreseeable future, finally decided to do the mini playfield rebuild I've been meaning to get to for about forever.

Just finished replacing the mini playfield itself, complete with the cliffys that I've had in a box for a year. Man, it sure would have been nice if that mini playfield had been dimpled..... Took forever just to make sure everything would line up correctly before dimpling it.... But I'm happy with the progress so far.

Before and after......

Quick question...... When I removed the motor/cam mounting bracket from the bottom of the main support bracket, I found 4 metal standoffs of various sizes between the 2 brackets. My understanding was that these 2 brackets should just connect to each other directly, with nothing in between. Are these supposed to be here, or is just some random previous owner hack-job?

Have you followed the service bulletin they released that addresses right/left cant?

Anyone have any suggestions for what material is the best to use to reproduce the shroud that blocks out the light for the optos in the 5-bank target on the mini playfield to function correctly? Mine is pretty torn up and I occasionally have opto issues. Would standard matte black paper be acceptable, or should some sort of fireproof/heatproof material be used? Thoughts?

Interesting.... My shroud doesn't have "sides"..... But then again, I'm past the point of believing what I see is what should be there. When I took it apart, I also found small pieces of cut up credit cards being used strategically when light must have been interfering with an opto. Classic stuff.....
