Namco Atari Pacmania New power supply. Newer Wells Gardner 19K7200 CRT monitor installed with no burn.
Everything works fine except the known issue - an audio tone is constantly stuck after first game over. Goes away after starting new game.
Doesn't seem to do it until restarting machine. In audio test mode- a couple audio tests stop mid way through playing. Might be problem with bad audio ROM chips?? You can ignore, turn sound down, or fix it.
