Are Vacuum Tubes Still Being Produced? Current audio vacuum tube production is still largely limited to 3 locations: China, Russia and the Czech and Slovak Republics. While many other developed nations still produce and develop vacuum based electronics, only Japan and Germany have produced glass vacuum tubes suitable for audio recently. What replaced the vacuum
What Does A Rectifier Tube Do In A Tube Amp? The function of the Rectifier Tube in a guitar amplifier is to convert AC voltage from your power source to the DC current used in the internal operation of the amp’s circuitry. Do power tubes affect tone? It has no effect on the sound. This
What Did The Vacuum Tube Replace? Vacuum tubes were originally used in the earliest digital electronic computers back in the 1930s and 1940s, before being replaced by transistors composed of semiconductors, which can can be manufactured much smaller, making today’s computers, smartphones, and tablets possible. What was the vacuum tube replaced with in the second
What Is The Difference Between 12AX7 And 12AY7? The 12AY7 tubes are not 12AX7’s and have many different properties. They draw more current than a 12AX7 as well as having different internal capacitance between elements and a different plate dissipation. Because of these differences, they sound different in a circuit designed for a 12AX7 tube.
How Long Do Tubes Last? You can expect a conventional amplifier tube to have a service life ranging up to 10,000 hours. Tubes with military specifications are built to last up to 100,000 hours. How often do tubes need to be replaced? On average, tubes can last from 500 to 1,000 hours, so if you
