I am another first time owner that bought a Williams Aztec. Game is in pretty good shape. One problem is that the game has a pretty loud buzzing - Must admit I am a bit of a noise freak and most people probably would not find it loud. When the ball gets put into play and starts scoring is when the buzzing starts. The buzzing stops when the ball is out of play and the scoring for that ball finishes. Hard to tell exactly where the noise is coming from but seems to be coming from under the top half of the playfield. Not really excited about taking the game apart and starting to play around inside - But I will if I have to. Any suggestions? Please do not hesitate to say: It is a 50 year old machine you idiot - It is going to make some noise. That might be the proper answer.
