I put a NOS picture tube in my Space Invaders upright. Picture looks fantastic. It looks like a brand new game. Do I need to check the B+ voltage? I didn't touch it. I'm not sure how to check it. I just want to make sure I'm not overdriving anything. The chassis was completely recapped a few years ago by Chad at Arcadecup. The chassis is a 19V1001 and the tube is a Phillips M47EAA7WD. I have a schematic but it's difficult to read. The instructions mention a signal generator. I don't have one. I would appreciate any tips on how to do this. Thank you.
