8 T ube Basics The 12AX7 and 12AU7 tubes will have a life of about 5,000 to 10,000 hours. The lives of powertubes are more difficult to predict. This also depends on how "gently" or "roughly" you use your amplifier . In general -under normal conditions- you can say between 2,000 and 3,000 hours.
9 Fuse Protection A note on fuses : If "someone who knows" tells you to wrap fuses with aluminium foil to avoid wasting money on new ones, it's best not to take his advice. Fuses are safety valves. They should always be replaced with the exact same value and type.
10 T roubleshooting Some tips: • No output. Power is on, but power LED is off and tubes do not light up. Mains fuse is out. Replace fuse as per instructions on page 9. • No output. Power LED is on and tubes do light up normally . Plate fuse may be out.
