My woofer in my Street Fighter 2 pin is pumping out an incredibly annoying hummmmmmming noise from the second you turn it on until it is turned off.

I can fix SOME things on a pinball machine but if it requires board repair I find someone to do it or get a new board altogehter. I'm not sure if it is a power supply issue or not. It does "work" but like I said, there is always a loud humming.

Connections appear to be ok all around so I don't think that is the issue.

If anyone thinks replacing the speaker (my prefered fix) would work let me know. I'm not a Speaker expert and am not sure if they don't just die after awhile and need replaced. I'm also not sure if this is a common problem on system 3's or not.

Could disconnecting the speaker altogether affect the machine adversely?

Any advice would be greatly appreciated! Thanks.

Ended up disconnecting it for now, I have it in my brewery and people were really annoyed by the hum. Think I may replace it down the line, will update if I do. No real drop in sound, doesn't detract from game.
