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). Having said that,
it is important to understand that _if_ a SE stage delivers inaudible levels
of distortion and the load is resistive (which it pretty much is, within
preamps), then there is no real problem. The problem with SE amplifiers is
when they are burdened by output transformers. The massive DC flux within
the transformer causes all sorts of problems, requiring heroic and
completely silly solutions. Solutions which can be found simply, cheaply and
easily by implementing that old idea of push pull.
