So, yesterday, a couple of notes:
1. Installed the simple noise isolater for sound bar. No more hiss.
2. Looked under playfield to ensure all major brackets are tight. All looked good. Just had the one flipper stop come off and had to adjust the spinning disc, like many others have done.
3. Forgot to check the shaker to see if everything is tight. Still don' like how the shaker doesn't have the same overall "feel" like WoZ. Will see if tightening things up in the shaker helps.
4. I'm still hearing a faint hum near the flippers for a few seconds. It doesn't happen specifically when the flippers are in use, so not sure where the sound is emanating from. Any ideas on what to check?
5. While playing a game, I had what looked like a special mode start up. I think it was called, "Do you want to play?" mode. Very cool. It looked like pin was resetting or rebooting and then it went into this special mode. Anyone else see it?
