Help! My old Vintage Club has a bad buzz/hum

[Pine Apple Slim]

Happened over the last couple of weeks and it's getting worse. The amp still sounds good, it just has hum from hell, like a bad ground or something.
Any ideas?

 

[Help!I'maRock!]

Bad tube?
Cold solder joint?
Crate?

Bad tube? Just changed em all about 3 months ago. Maybe, but the amp still sounds good.

Cold solder joint? Could be, or a loose one.

Crate? I guess, but it's lasted me 20+ years.

I think I'm just gonna replace it with an Orange Crush 35rt.

I would spay all the pots and, jacks with Deoxit.

Had that happen once with the ENGL I had, and that time it was a power tube that had gone bad.
