My Blues deluxe has started "popping". Its loud and irregular' It is doing this whether an instrument is plugged in or not. Pops on both channels and volume adjustments have no effect. Ideas? :?

Check power tubes first.
You can do this by unplug all other tubes ( 12XX7 ) and listen.

Popping ; replace Power tube with bias check
No popping ; could be a 12XX7 tube

Popping could be a bad solder or contact in power supply circuit

If rotating or changing the tubes doesn't help --- it could be a cold solder. Tapping the solder points with a WOODEN chopsticks (or some similar non-conductive tool), may reveal the cold solder point.

I'd do the sockets and jacks, first. They tend to be the culprits.

Good luck! :)
