My Deluxe Reverb reissue (~3 years old) has started intermittently sounding a bit dull. As with lots of sonic things it's difficult to describe – it's not an abrupt change, it will sound okay for a few minutes and then gradually start sounding a bit lifeless, and then fade back to sounding a bit better, but never at '100% tone'.
I haven't ever changed the tubes so that was my first thought; on inspection in the dark I noticed one of them was glowing blue in unison with the chord I was playing to test:
This morning I swapped the two 6V6s around, and the same thing was happening in the same socket with the other tube (i.e. the tube in the socket furthest from the rectifier glows blue independent of which tube it is), so it wouldn't appear to be an issue specific to that tube.
I use an attenuator with the amp (UA OX) all the time, but only ever run it around 4.5 on the volume (clean but just getting a hint of breakup if you really hit it). The GIF is recorded with the amp on 10 (and the speaker off!).
I was about to buy a new set of power tubes but this seems like it might be an amp issue? Or maybe normal behaviour?
