Vacuum Tube Theory from Soup to Nuts

Vacuum tube (or also called valve in Great Britan) is electronic component / device used in audio industry mainly as amplification component before transistors were found.

The phrase "high technology" is perhaps one of the more overused descriptions in our technical vocabulary. It is a phrase generally reserved for discussion of integrated circuits, fiber optics, satellite systems, and computers. Few people would associate high technology with vacuum tubes. The notion that vacuum tube construction is more art than science may have been true 10 or 20 years ago, but today it's a different story. The demand on the part of industry for tubes capable of higher operating power and frequency, and the economic necessity for tubes that provide greater efficiency and reliability, have moved power tube manufacturers into the high-tech arena. Advancements in tube design and construction have given end users new transmit­ ters and RF generators that allow industry to grow and prosper. If you bring up the subject of vacuum tubes to someone who has never worked on a transmitter, you are likely to get a blank stare and a question: "Do they make those anymore?" Although receiving tubes have disappeared from the scene, power tubes are alive and well and are performing vital functions in thousands of divergent applications. Solid-state and tube technologies each have their place, each with its strengths and weaknesses. Tube design and development, although accompanied by less fanfare, is advanc­ ing as are developments in solid-state technology. Power tubes today are designed with an eye toward high operating efficiency and high gain/bandwidth properties.

Vintage synthesizer featuring Vacuum Tube Synthesis with vacuum tube circuit modeling that perfectly captures the crunchy, warm sound of the analog era.

Vacuum Pro is a polyphonic analog synthesizer with vacuum tube circuit modeling that perfectly captures the crunchy, warm sound of the analog era. With four analog oscillators, multiple filters and envelopes, and built-in audio effects, Vacuum Pro lets you dive deep into subtractive synthesis to recreate those sought-after analog sounds from the 70s and 80s. Tweak the switches, knobs, and dials to program anything from basses, leads, pads, or unique sound effects. For even more warmth, Vacuum Pro has six virtual vacuum tube circuits that add crunch and grit at every stage of the signal path. Analog just got a whole lot warmer.
