Help - static noise in speakers

Could just be dirty signal tube pin to tube socket connections. Pull and reinsert signal tube(s) in tube socket a few times. The friction should clean the connections.

Swap the left and right tubes and see if the static moves to the other speaker! If it does you have a bad tube!

Did you try swapping the left and right channel tubes?

The static noise could be caused by a cold solder joint/connection. Or possibly a poor internal wiring connector connection.

I did a quick look through the owner manual of the amp.... That amp is basically controlled by a computer.

May not do a thing, but did you try unplugging the amp from the wall outlet for a few minutes then plug it back into the wall outlet?

IMO, it's not the tubes. If it was the tubes, switching the tubes from one channel to the other the static would have followed the bad tube.

I also just plugged in headphones and I don't hear the static.

IMO, that says the preamp section is ok. That would include the tubes. The static is in the solid state amplifier section.

Any noise due to external factors would show up on both channels, my best guess of OP issue is failing cap, resistor, cold solder, either diy repair or return to manufacturer, let them diagnose, this all speculation at this point.

Not really.

I imagine the internet cable the OP moved was on the same side of the amp’s  connected speaker. Just a guess the static sound started recently when the OP moved the internet cable in close proximity to that side of the amp.

Quick check, move the internet cable back in the same spot as before producing the static sound. Static sound back again? Move the cable away again. Static sound gone? The OP just saved himself a bunch of money thanks to @oddiofyl .
