I'm working on a pacman for a friend and there was a really loud hum. Pacman sound would play but, the hum was overbearing the game sounds. I've already diagnosed the problem to be c51 in the audio section. It is a 330uF 16v cap. I don't have any of those. Can I replace it with a 470uF or 220uF instead? According to the schematics, it goes to the non-inverting side of one of the dual amplifier chip. I don't see a problem with doing that but will is affect the sound?
