Hello all! I just started in this hobby and I am really enjoying it. So far I have a really nice SST and Corvette pin. Today I purchased a Sega Baywatch. I have 2 questions. How do you adjust the volumn on this pin? Second, while I was trying it out at previous owners house it played really well. After i got it home and did some cleaning and changed some bulbs it now makes a pulsing noise that I am pretty sure is coming from the large solenoid thats right buy the area where the balls are initially launched. It just seems to keep on cycling. Makes this noise then eventually stops. When ball drains it will start doing it again. Did I mess something up while changing bulbs? It wasnt doing this at previous owners house. Thanks for the help!
