I had a question about how the playfield is supposed to rest in the steel channel. I've attached a few pictures here.

My first question is, which rubber feet am I supposed to be using to rest the playfield? There are three sets... two with metal around it, and one without.

But regardless of which one I am supposed to be using, the rubber feet don't rest on the flat part of the steel channel. This is because the notches in the channel don't line up with the metal bars that you pull. Are the notches supposed to line up? Right now, no matter how I place the playfield down, it's metal on metal.

Anyone getting a buzzing when the action picks up? Like when the shaker is going or when the music is a bit louder I get a buzzing on the right side about half way up the machine. It sounds like it’s coming from the rail that holds the glass.

Follow up to my post about rattling...

I found two sources of rattling for anyone else that gets this.

1. The tilt sensor bob was rattling against the hanger. I fixed this with a rubber washer jammed against the top to stop it from doing that.
2. The side rails are held on with some adhesive. On my machine, the adhesive is giving away. So when the game action ramps up, the rails are quickly making contact and then braking the contact with that adhesive, leading to a loud buzzing. No idea what to do about this yet. I have contacted jersey jack, but haven't heard back from them.

No... the hanger goes through the middle of the bob and has a washer holding it at the bottom. But at the top, the bob is free to rattle against the hanger. So when certain music hits just the right frequency, the bob would rattle against the hanger. So I put a rubber washer on the top of the part of the bob so it can't rattle anymore. But it doesn't interfere with the electrical connection or the ring of the tilt sensor.

Here is the bob. The rattle is coming from the bob rattling against the hanger. You can see the rubber washer I used to wedge against the top. I also put a rubber washer on the button below the bob agains the plastic wing nut.
