Safety Tips for Working On Tube Amplifiers
Vacuum tubes require a high voltage to operate, this means you can get electrocuted, or burned. Do not place your hands or non-insulated tools in the amplifier when it is plugged in. When probing a live amp, keep one hand in your pocket - it's the current across the heart by way of the arms that kills you. Electrolytic (and other type) filter capacitors can hold lethal charges - be sure to discharge them before working on an amplifier. Don't install tubes with the power on.
