I sent out my boards to get repaired and had no idea what an ordeal this would be. I am so grateful that somebody out there knows how to repair PCBs. I highly recommend Classic Arcade Repairs. Can't wait to get this back in my Cabaret machine.
Update: The following is from Sean at Classic Arcade Repairs. Well, I have the Space Encounters PCB set working perfectly now. It is basically a brand new PCB set. It only has two, yes just two, original logic chips remaining. I replaced 80 74 series logic chips on the set. You have to be 100% certain that your power supply is outputting the proper voltages before hooking it back up. I have completed the entire set (including the audio PCB, which also had every single chip bad on it). I can honestly say, I have never had a set like this come in for repair. Nearly every single chip was replaced lol. I hope you don't get too much sticker shock at the invoice total.
