My 1.5 year old VT15 is acting up and sounding terrible.
-Regardless of the setting or amp model, I am getting loud high frequency hiss and static.
-The noises occur during single notes and chords.
-A month ago, after removing the chassis from the cab, I discovered the tube leaning at 45 degrees.
-The tube had popped out of the retainer and was barely hanging on.
-Fixed the problem and the amp sounded great.
-Now, hiss and static again #@#!!
Should I replace the tube now?
The Amp has not been handled roughly, so I don't expect the tube to move again.
