VACUUM TUBES DEFINITION (continued): … . However, tubes are still used in some high-power amplifiers, especially at microwave radio frequencies and in some hi-fi audio systems.Tubes operate at higher voltages than transistors. A typical transistorized amplifier needs 6 to 12 volts to function; an equivalent tube type amplifier needs 200 to 400 volts. At the highest power levels, some tube circuits have power supplies delivering several kilovolts.Vacuum tubes are making a comeback among audiophiles who insist that tubes deliver better audio quality than transistors. These old-fashioned components are more electrically rugged than their …
