LEAK TL/12 Point One Amplifier. The first commercially produced amplifier with distortion of 0.1% was the LEAK Type 15 "Point One" of 1945, using KT66 vacuum tubes (valves) connected as triodes, with 26 dB feedback over 4 stages including the output transformer. In 1948 LEAK produced the TL/12 which was also rated at 0.1% but featured improved ...
The tubes best fitting the circlotron concept are triodes designed for use in power supplies as series regulators: 6080/6AS7, 6C33C, 6C19P. An amplifier with one 6AS7 dual triode per channel (R p = 270 ohms, [4] μ = 2) will have a Z of about 67 ohms—sufficient to drive most headphones.
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.
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 ...
Valves with high g m thus tend to have lower noise at high frequencies. In the audio frequency range (below 1–100 kHz), "1/f" noise becomes dominant, which rises like 1/f. Thus, valves with low noise at high frequency do not necessarily have low noise in the audio frequency range.

Vintage Series changed to a solid state pre-amp & a Master Volume (which is the easy way to tell if the amp has 6C10 pre-amp or not without removing the back panel to access the chassis), the solid state preamps and 6L6GC power tubes.
