IN RESPONSE TO THIS

You really have to wonder.

Here we have three self-proclaimed engineers claiming that Class A is
an amplification Class in which "the output device(s)never cease
conducting under any signal condition."

The three "engineers" in question are Graham "Poopie" Stevenson, Don
"Bluster" Pearce and Arny "I spoke in error" Krueger. Apparently they
are perfectly unable to understand, after they have been told so a
handful of times already, that "any signal condition" includes
overdrive which turns even the correct part of the definition into
absurd nonsense.

Here's the sequence of their errors, with a small sample of their
abuse liberally spattered over the newsgroups:

First Andre Jute, he of the saintly patience, pointed out that Poopie
Stevenson made a silly error:

Poopie's absurd redefinition of Class A as
a Class in which "the output device(s)never cease conducting *under
any signal condition*," (emphasis added). It's ludicrous.

Then Poopie Stevenson confirmed:
It's actually the only accurate definition.

And Arny "I spoke in error" Krueger agreed without any qualification:
Agreed.

Then Andre Jute, he of the saintly patience even with fools, pointed
out that the two parts of redefinition are mutually exclusive:
Any amp can be driven out of class by excessive signal voltage.

Which Poopie tried to blow away with poor-quality smoke:
Overdriving to cut-off is merely gross abuse and a complete red herring /
irrelevance.

Fully supported of course by his yes-man, Arny "I spoke in error"
Krueger:
Agreed. Jute seems to be addicted to excluded-middle arguments. Kick out
those and the straw men, and he's hardly have anything to say. ;-)

Now Don Pearce tries to bluster the argument out with an obvious lie:
Can you overdrive a class A amp to cutoff? In my experience what
happens when you overdrive a class A amp is that one device saturates,
and the other sticks with its normal bias condition. There is no
circumstance in which I have ever managed to put a class A amplifier
output device into cutoff.

d

Of course, it is irrelevant (perhaps even commendable) that Don Pearce
lives such a dull and unadventurous life that he has never overdriven
a Class A amp; perhaps he doesn't own a Class A amp; on the evidence
in this thread he doesn't even know what a Class A amp is. What
matters is that Don Pearce, like Arny Krueger, supports Poopie
Stevenson's absurd definition of Class A operation as 360 degrees of
conduction "under any signal condition".

How can any properly educated engineer not know that the signal in an
amplifier class is by necessity limited?

It is difficult not to conclude that these three clowns, Stevenson,
Krueger and Pearce, are either not engineers, or were not properly
educated, or are too old and fat and slack to remember the basics they
were taught.

I have on previous occasions demonstrated what Poopie Stevenson's
claim of a University of London degree actually means: not very much,
as he got his degree from a jumped-up polytechnic (a British version
of the soldering schools Ludwig is addicted to) forced onto UL by a
socialist government trying to save a buck. Others have noted that
Krueger was "educated" at a community college I have never even heard
of. Who knows where Pearce was so misshapen as to believe that it
doesn't matter how much signal voltage you use in an amplifier?

Poopie Stevenson, Bluster Pearce and Erroneous Krueger are, in
engineering terms, ignorant and abusive clowns "under any signal
condition".

Just goes to show that Jute is so stupid and arrogant that he is willing to
go on record agreeing with the sockpuppet known as George Middius. AFAIK,
the lie that I ever attended a community college is a lie that was
originated on Usenet by the Middiot.

You're tight, Krueger, I merely reported what others said about you.

I graduated from Oakland University

Never heard of that one either. The rest of your post is poor-quality
smoke to avoid the main issue:

So, Arny "I spoke in error" Krueger, where is your excuse for claiming
that Class A must hold true "under any condition of signal"?

which has never been a community
college. It is the only degree-granting institution of higher education that
I've ever attended. True, there is an educational resource named Oakland
Community College, but it is a completely different institution.

The rest of Jute's post is about as truthful as this false claim.

Do you, Arny "I spoke in error" Krueger, deny that you agreed with
Poopie Stevenson that Class A must hold true "under any condition of
signal"?
