Sonzera 20 combo issues...

[Dr Improbable]

Hello all!

I bought a Sonzera 20 amp, new, in June. It has always had a noise/hiss to it, but I like the tones, so I put up with it. Lately it seems like the noise is louder, and I'm getting an occasional rumble sound. I know this sounds like output tubes, but I got it new in June!

If anyone here has experience with these issues, please chime in. I could use the help!

I don't have a Sonzera, but that def sounds like a tube issue. It's not regular, but tubes can go bad any time.
