Splet20. jun. 2013 · A vacuum tube device's heater filament can be supplied with either DC or AC, the tubes work the exact same way with either type of supply: The heater is simply using the power for resistive heating. The voltage to be supplied would also be the same, i.e. if a tube is rated for 12 Volts, then one uses 12 Volts DC or 12 Volts AC.

Solid State refers to the technology of using transistors for the "electronics". Tube refers to the older technology that was common in the old days. SpletThe tube is popular in hi-fi vacuum tube audio as a low-noise line amplifier, driver (especially for tone stacks), and phase-inverter in vacuum tube push–pull amplifier circuits. It was widely used, in special-quality versions such as ECC82 and 5814A, in pre-semiconductor digital computer circuitry.
Splet14. dec. 2024 · Vacuum tubes are an older technology not often used today, but they still show up in some amplifiers and other devices. For a quick test, inspect the tube for signs of damage and listen to the sound it makes. If you're familiar with tubes, you can also get a tube tester with a testing chart. A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by second-generation transistorized computers, vacuum-tube computers continued to be built into the 1960s.
