Tube/socket issue

[headlessdeadguy]

Plugged in my Granger last night. Had no sound. Smelled something burning and found this. This amp was just shipped so there is a possibility that the tube wasn’t seated well. Question is, do I put another set of tubes in and see what happens or get it to a tech?

You can try scraping the carbon off and gently cleaning it with some alcohol and replacing it with another tube. Is it scorched under?

Probably took the screen resistor with it.

Pull the chassis, look underneath & see if there are fried components before you fire it up.
If you're not comfortable with that time to bench it.
Check the fuses.
