Nanao ms-2931 buzz

[Arcade-Projects]

Been living with this for a while but I feel like I should address it now that flybacks are available. If it’s the flyback... I don’t see any cracks or arcing.

this buzz is pretty consistent, I do think it gets slightly louder as the tube warms up. It will buzz at a higher rate at 24 or 31khz, though I didn’t film that tonight.

I’ll probably pull off the shield tomorrow and see if the neck board is vibrating, but, any other ideas on what to check, oh CRT wizards?
