The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, who were owned by Philips. [1] The EL34 has an octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between ...
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.
A valve RF amplifier (UK and Aus.) or tube amplifier is a device for electrically amplifying the power of an electrical radio frequency signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of ...
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]
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.

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.
