Hello there!

I recently got this Fender Champion 600 from 2007, but clearly something is wrong with it. The is like a fizzy sound in the background, no matter if you play light or hard, low or high volume. The amp is all stock including the tubes. I swapped the 12AX7 for a known good one and the problem persists. Any Ideas on what could be?

Thanks in advance for your time!
