Face facts, Witless -- the Krooborg stepped in the doo-doo again, and now
it's getting its comeuppance.

No, Arny was actually totally correct and John Atkinson has merely introduced
a red herring.

That's one possibility. The other (and much more likely) one is that
you're a doddering old fool who can't even remember the day of the week,
let alone how amplifiers perform in real-world applications.

I'm pleased you can see that. Maybe you're not entirely brain dead ?

Poopie tries the Kroogerian "selective editing" ploy.

That's the first step toward solving your problem, Donkey.

I hate to interrupt this fine flame war :-) But back in the early
70's, table radios made the transision from the "All American 5ive" tube
circuit to a solid state circuit that used a high voltage bipolar
transistor and output transformer for the audio output. Looking at the
collector side of things, it behaved like a pentode. Look at the curves
of a vacuum tube pentode, and then a bipolar transistor with respect to
output current. The inputs are different (voltage vs current) but if
you ignore that, they look pretty similar. So it should be possible to
build a SS amp that sounds like a pentode amp. But that's not triode
sound...

But pentode curves are significantly different from triode curves, and
triodes tend to be many tube fans' favorite device. And it's not easy
to get a transistor to act like a triode.

I'm not sure exactly when this transition was made, but I do know that
it occurred sometime well before the "early 70's", I would say that the
transition occurred in the mid 60's, I know from personal experience
that these radios were already in production by late 66, when they first
went into production I don't know.

I thought the common bipolar transistor was a "triode".

I was thinking of the SS radios that were "hot chassis". The audio
output transistor had about 100V B+ on it. Before these, there were
some SS radios that had small power transformers and were essentially
portable circuits inserted inside a table radio cabinet. But it's the
hot chassis high voltage transistors that ran in class A "single ended"
I was thinking of.

My Chinese friends tell me that the word "transistor" translates into
"crystal triode" in Chinese. :-)

No, it's a transistor.
