Bugera v5 - tube replacement light on: eplaced tubes, still crackles, no volume help

Contributor - Level 2

So about a week ago, I turned up the Bugera V5 to about 8 or 9. Suddenly a loud crackling sound, the tube replacement indicator light turned on, and I had choppy, crackling sound coming out of the amp.

I replaced both tubes. Turned on the amp and nothing changed. The tube replacement light comes on, the speaker crackles and I get very little volume.

When the tubes are warming up, there's no tube replacement light, but after about 20 seconds, the tube replacement light turns on. Also, I can get a little clean sound out of the amp toward the end of the warm up cycle, but it immediately drops and the crackling begins again.

Have I killed the amp? Is there something else to look at?
