I picked up a Gottlieb 300 for $80 last weekend. All of the fuses had been pulled, but it looked okay otherwise. The cabinet was clean enough, and it didn't look like there had been too many questionable repairs done. The owner's father bought it for the family over 30 years ago. She said it quit working many years ago.
You know how the ads always say probably just a fuse? Turns out, that was true in this case. I put in new fuses and got lights in the backbox. After seeking advice from a local EM legend, I got it up and running and somewhat playing a game. The coil that kicks the ball into play seems to be dead, and steppers need to be cleaned - not advancing players.
I started cleaning it up today, and thought I should share photos before I go much further. It smells like cigarette smoke, but overall was not much of a mess. All of the plastics are present and in excellent shape - I removed them today to begin cleaning. I have all of the missing inserts too. Every time I raised the playfield, another fell out.
