Small is also beautiful. The small is the genesis of the large.

It's funny that some cannot grasp this fundamental concept with
single
ended triode (SET) amps. We routinely build preamps and voltage
multiplication stages of triodes operating single-ended, and the
diehards who with a convulsive kneejerk reject any amp without a
push-
pull power stage will be the last to let go of the single-ended gain
stage, yet they cannot see that the small signal stage is a template
for the sweetest power stage.

What is sauce of quail must be sauce for the goose and the gander
too.

Very difficult to understand how some people think.

**Speak for yourself. The best valve preamps I've ever heard are push
pull (Alan Wright's fabulous balanced preamps spring to mind).

And those pre-war WE cinema amplifiers that were referred to in another
thread had one or two stages of push-pull amplification before the output
stage. But then they were money-no-object designs, designed to produce the
best performance possible with the technology of their time.

**Pre-zactly. Since the advent of push-pull, SE has been negated, except in
cheap, crappy amplifiers.

Trevor Wilson

Let's hear that again?

Since the advent of push-pull, SE has been negated,

Then why are you spending so much time, Wilson, trying to stem the
tide of SE amps chosen by sophisticated music lovers?

except in
cheap, crappy amplifiers.

Eh? Most SE amps built or bought by audiophiles are not far off the
price of a reasonable used car.

Do you ever reread these vomitings you send out, Wilson, and reflect
that their irrationality and ignorance cannot reflect well on you?

Unsigned out of exasperation with this idiot Wilson

Andre,

You had this discussion with Trevor back in 2005. Your point of view,
quoted below, was distinctly different then.

From the Google groups archive, December 18, 2005, Andre Jute wrote:

"The truth is, Trevor, that my personal taste and the winner in blind
tests with the musicians (still unspecified, if you don't mind) I like
to use, as well as other qualified persons, is for small Class A
push-pull trioded pentodes operated at low power with zero negative
feedback. The best amp I ever designed is my T113 Class A PP EL34 in
triode mode (its switchable, actually) with zero or very little
negative feedback (also tunable in my own copy). That doesn't mean I
abhor SET or solid state. I have and use both, too. Nor does the choice
necessarily have anything to do with your reasons above."

Yo Bro', whassup wid dat?
