Talk:Single-ended triode

message: "Audio power triode is biased to Class A operation by applying negative bias voltage to its input grid (see diagram), or by raising cathode potential with fixed bias network."
I dont see any need for it to be fixed bias. Indeed automatic bias is more popular.
I've made a couple of small tweaks so the article represents SETs as a whole rather than one currently slightly fashionable corner of it.

thread_title: Bias fixed or automatic

message: This ought to be mentioned in the article.  SETs have SIGNIFICANTLY higher levels of harmonic distortion than other designs, and many in the high-end audio community argure that they owe their "sound" not to purity but to the introduction of nice-sounding (bot not accurate) even-order harmonics.
Something of this controversy ought to be mentioned  —Preceding unsigned comment added by 98.206.43.107 (talk) 10:46, 10 June 2008 (UTC)
thread_title:  SETs introduce harmonics that were not in the original signal to a greater degree than other amps- "euphonious distortion" 

message: Plate or Anode resistance.
Plate resistance or "rp" is the word used in all textbooks over the last decates.In fact this is not correct. That would mean that; DC idle current flowing through the electron tube (valve) because of the fixed plate voltage. It is however the change in plate current, ensuing from a variation in the plate voltage, while keeping grid and cathode voltage constant. So the correct word should be "Plate impedance" or an amelioration for "plate impedance" should be "Anode Impedance"

thread_title:  Anode impedance 

message: This is an example of a new concept that I have coined AudioFOS:
: .. have achieved a cult status because of their excellent midband performance (argued to be the most important part of the audio spectrum in music reproduction)[citation needed], musicality, and directness. This perceived high sonic quality is mainly attributed to the simplicity and minimalistic approach of the circuits involved and the triode amplifying tubes that are typically used.
This is so far the purest of the verbal feces that I have encountered saturates tube amp descriptions: AudioFOS.  Triodes don't amplify was well as tetrodes or pentodes because they don't have extra grids to combat the Miller effect, but it is these grids that add distortion in tube amps, and hence the desire for low output but clean triode amps.--John Bessa (talk) 00:47, 2 October 2011 (UTC)
