When you have red plating with tube amps until one measures plate voltages you won't know for sure if its tube failure or amp issue, you may be damaging more tubes if amp is the issue. Tubes going bad without red plating likely lost vacuum, sometimes this seen as interior of tube enveloped in blue haze, other times not, another sign is white getter.
Can using a bad tube hurt an amplifier?
If you're using a tube for a while, and everything's fine, and then voltage changes over time gradually, and then it damages an amplifier? are amps Built with controls to prevent that from happening?
How can you trust using a tube if it potentially could harm an amplifier?
Assuming You're using the correct tube in the slot provided.
