This and all Tone Priest videos are for edu-tainment purposes only. Vacuum tube amplifiers can have lethal voltages in excess of 700 volts. Capacitors can retain a deadly charge even when an amplifier is turned off and unplugged. Videos are not instructional nor do they advocate anyone doing any kind of repairs on their gear. Nobody should do electrical work on anything for any reason ever. Keep your hands and belongings inside the car at all times.
