So I love being on my EZG-50 like 3 hours a day. I get some clicking noise that seems to be coming from the tubes. These are the stock tubes. Can someone inform me what the noise means and if it is normal? Doesn't bother me too much. It's only when I am not creating music that I can hear it. It is also random and happens anywhere from a minute apart to an hour apart.

Is your cell phone near your amp? Mine makes the amp "tick" like a time bomb.

Some tubes, especially preamp tubes in the front end can do a ticking or popping when there is a defect in the tube where there are impurities and they act to form something of an internal capacitor of a sort and this do this clicking. In the GT-12AX7M this was not uncommon and in many cases would go away after the tube was warmed up for a few minutes.

Sometimes a clicking noise can be RF from an "underground fence" for dogs. Also electric fences to keep livestock in and coyotes and the like out click.
Whoops I just read it again and the intermittent part... It could be a refrigerator/freezer compressor, furnace motor, well pump or washing machine starting and/or changing modes.

This still sounds to me as if it is a preamp tube in the front end.
Easy to verify .... pop in a different preamp tube for a while.
