I must really love punishment, because here I am again fixing another EM pinball machine. I can’t help it though, their tendency for faults aside, EM’s are beautiful machines and every line up should contain at least one. This time I’m looking at another baseball themed machine by Gottlieb, appropriately (maybe boringly?) named “Baseball”. It was released in 1970 with around 2350 units shipped. It came out about a year before Playball (which I fixed up recently) and both machines share a very similar playfield layout and feature set. This isn’t my machine and I’m simply repairing it for someone else (the same guy owns the Playball I fixed up and documented recently). It’s not a restoration, just a fix up for the issues it’s having.

At the end of my previous update, I was really close to having the repair work on Playball complete. I haven’t had as much time as I would like lately to look at the machine, so it dragged on a little longer than I had hoped. The time has come though to get the machine running 100% and returned to its owner. I had two issues on my plate to deal with. The first was the third base lamp occasionally not lighting up when it should and the second was the score motor continuing to run intermittently during play. The third base issue turned out to be a dirty shoe on the hit unit. I had somehow missed cleaning it along with the others in my last update. Nice and simple. That just leaves the dreaded score motor.
The first issue I wanted to look at was the lack of sound. Although I could play a game on the machine, I got no sound at all in most cases. When I could hear sound it was very very quiet or distorted.
I went into maintenance mode using the switch inside the coin door and to the sound test mode. I couldn’t hear anything.
There is a volume control inside the coin door which I adjusted. Again no sound.
Next up I wanted to check the plugs and sound board in the head box.
