Can you think of another topology (other than one using class C maybe )

You want *me* to make your case, Poopster? No, no, no, that's not how
debate works all all. Krueger makes the claim, then it is up to Krueger
and his busy little elves like you to prove it when it is challenged.

In theory SET dogma reduces a certain type of distortion, but in
practice it's unsuccessful because the cure is far worse than the
disease.

Obviously Jute you know nothing about how arguments work. Your silence makes
Graham's case. Your immediate obfuscation made Graham's case. By not
providing an immediate cogent answer, you made Graham's case.

In short Jute: Y-O-U L-O-S-E!

Thanks for playing.

Can the next contestant come up to play?

SET advocates believe all phase splitters are imperfect and so
eliminating them eliminates asymetric drive issues, also that push-pull
transformer cores are magnetized and unmagnetized on each cycle.
However, even if that's so the core magnetization is ten times worse,
making sufficient primary inductance impossible for good LF response if
HF response is not to be killed off.

It should be noted out of fairness in the case of a deliberately
restricted bandpass amplifier, perhaps one for a treble driver, single
ended can provide better results than at first it would appear. The
Audio Anthology provides the example of a treble SET for a horn driver
that provides 4 watts, and by limiting power protects the driver since
it will handle at least three times that in square wave power at 50%,
symmetrical duty cycle.

Actually I asked for a comment on distortion levels vs amplifier topologies.

It's not a 'case' at all. It's about comparing things.

No, no, no, that's not how debate works all all.

Yes it is actually. Maybe you didn't get it ?

Krueger makes the claim, then it is up to Krueger
and his busy little elves like you to prove it when it is challenged.

A.K. made no claim as far as I can see in this thread.

In fact it was you who started it as a supposed denial of A.K's comment in an
entirely different thread.

Thank goodness for real design engineers !

I wonder who actually 'ghost writes' the techy bits on Joot's site ?
Clearly Andrew isn't up to the task. Making quasi-technical verbiage is his
style as opposed to anything of substance.

Poopie Bear has been perving Andre Jute's netsite again:

Poor old Poop can't find anything to criticize, so he issues an empty
smear.

Clearly Andrew isn't up to the task. Making quasi-technical verbiage is his

Except that on my netsite, as he just told us, this hypocrite found
"technical bits" incontestably so competent that he thinks I must have
hired an engineer to ghost them for me.

Of course, the above problems don't occur in a *solid state* SE amp
such as the Nelson Pass Zen or my own KISASS - but that's not a
recommendation for either in any absolute sense. You see, the fact
that SET lovers *believe* that there's something mysteriously 'wrong'
with phase splitters doesn't make it so.

1) It's certainly possible to make a push-pull amplifier with complete
symmetry, tubed or SS.

2) SET amps are *extremely* assymetric by nature, so that argument
kinda falls on its face at the first hurdle.

Amazing. I have several copies of the RDH so I can read it anywhere,
like a bible. I have never seen anywhere in the RDH anything to support
Krueger's claim. I'll deconstruct Krueger's silly claim later.
Meanwhile, could I suggest politely that you compare Krueger's claim
carefully to those pages before you embarrass yourself by posting page
numbers on which I shall demonstrate clearly that Krueger's claim is
not supported, in fact, quite the opposite. I wouldn't want a
fellow-Australian, even a silicon-head, publicly to fall into the same
trap as a recklessly blustering American like the thief Bret Ludwig.
Your disgrace may reflect badly on Patrick and Phil and me and several
perfectly decent, if misguided, fellow-countrymen on RAO.

Asymmetric drive - small problem
Asymmetric output stage - large problem

Typical toob bigot logic - exchange a small problem for a large problem!

also that push-pull
transformer cores are magnetized and unmagnetized on each cycle.

Only a problem to people who don't believe in soft magnetic materials.

IOW, instead of being an utter unmitigated disaster, its merely a disaster?

that provides 4 watts, and by limiting power protects the driver since

Sounds like a good job for a $1.00 (or less) IC.

Now that Krueger and his gang of thugs have worn each other out with
mutual masturbation about how they've won this argument before it
started, I have made a fresh thread actually to start the debate. To
anyone who made a contribution here in perfect goodwill, I can only
say, all is not what it seems. See the thread "PART TWO "SET dogma

explanation.

**I am quite happy to discuss the merits of various amplifier technologies.
Patrick, for instance, steadfastly refuses to address the following points I
made about SE(T) amplifiers:

---
* ALL SE amps suffer from even order harmonic distortion, which is
automatically reduced by using push pull topology. IOW: All things being
approximately equal (same output valves, high quality iron, good power
supply, same bias current, etc) push pull will outperform SE.

* ALL SE amps suffer appallingly bad load tolerance. IOW: A 20 SE amp (at or
near clipping) will deliver 10 Watts @ 4 Ohms, 5 Watts @ 2 Ohms and so on.
Unless the user has an almost resistive load, then severe power problems can
be expected. This problem can be eliminated by using push pull topology.

* SE amps are MUCH less efficient that a similar power PP amp.

* SE amps, generally, exhibit higher levels of hum and noise than PP amps.

* SE amps have a lower damping factor than a similar PP amp. This may lead
to audible frequency response problems, within the audio range.
