Check this out...
It's from the London Power guitar amp FAQ's...
"If your tubes are glowing bright orange - that is, the grey parts inside the tube are glowing
orange - TURN THE POWER OFF IMMEDIATELY! This is a bias failure in action.
Usually, this is the fault of the tube itself, but can also be caused by an open grid resistor,
bad socket connection, or poor solder connection. Check the bias voltage right on the tube
socket with no tube plugged in. If the bias is okay, plug in a new tube."
