I have an original Galaga machine which I am having a few pcb issues with. First off, it works and plays fine, but it has a few glitches. Here are some of the symptoms.
1. I have all sounds, EXCEPT for the explosion sound. That is the only sound missing.
2. The speaker hums pretty bad, and noticed the MB audio amp has been replaced before.
3. Later on in the gameplay, the "Ready" text will appear before you shoot all the aliens. Sometimes it appears at random.
4. Sometimes the it will go to "Game Over" for no apparent reason.
5. When your ship is captured, I shoot the bad guy, but it does not give me my double ship.
So far I have replaced the main caps, cleaned all the chip legs, cleaned the sockets, and looked for broken traces. Checked the original PS voltage from the board and it's kinda high, but I have another Galaga cab with a switcher, and get the same issues. Any help would be appreciated.
