Vacuum tubes used in electric guitar amplifiers. Particularly the ones that played important role in shaping modern image of tube sound , as well as notable former and current manufacturers of those tubes.
Prices for new 300B tubes ranged from US$175 to $2,000 per matched pair. Western Electric (tube manufacturer) , a small, privately owned company in Rossville, Georgia resumed production of the original 300B in 2018 using the original, 1938 manufacturing standards on a modernized assembly line housed at the Rossville Works.
The tube was used in a number of American guitar amplifiers; the Gibson Guitar Corporation, for instance, used the 7199 in 1961's Falcon for the reverb circuit. [3] Ampeg also used the 7199 extensively. [1] Notable is the Dynaco ST-70 stereo amplifier introduced in 1959 which used a 7199 tube in the driver section of each channel.
The amplifier is a high-end model designed for audiophiles, costing $15,000 or more. It can produce from 14 to 20 watts (at 8 ohms) per channel. This is considerably more than the standard 10w per channel from a typical 300B amplifier. Like all their products, the amplifier is built in America. [8]
While Tesla vacuum tubes were exported all over the world, and were known for their quality, the company did not survive the change of economic system after 1989 in combination with the downturn in the vacuum tube market. JJ Electronic was founded in 1993 by Jan Jurco, using the old Tesla machinery for the manufacture of vacuum tubes.
The simplest klystron tube is the two-cavity klystron. In this tube there are two microwave cavity resonators, the "catcher" and the "buncher". When used as an amplifier, the weak microwave signal to be amplified is applied to the buncher cavity through a coaxial cable or waveguide, and the amplified signal is extracted from the catcher cavity.

A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.
