You are JOKING !

You can't understand much about modern solid state design.

Even the true complementary pair was essentially unknown 35 yrs ago.
And
that's for starters !

35 years ago was 1971, and I had been building and repairing SS amps for
about 8 years at the time.

The true complementary pair was well-known and widely used in 1971. For
example, they were widely used as drivers for quasi-complementary output
stages. Common part numbers were 2N3053 and 2N4037 if memory serves.

As *drivers* !!!!!!!!!!!

You never said complementary pair of what.

" complementary output " has a *very* clear definition as far as I'm concerned.
That's why your example is called a " quasi-complementary output ". No
possibility of misunderstanding at all.


However below, I show a amp
design from 1967 below that had complementary pre-drivers, drviers, and
outputs.

Please pay attention Arny !

Say what you mean.

Pay attention to detail.


I said ' complementary output ' - NOT - ' quasi-complementary output' !
There's
a HUGE difference.Not least in the sound.

Actually, the post I responded to does not contain the word "output" or any
synonyms.

Now you're being obtuse.

Anyone with any relevant knowledge would understand full well what I was
referring to !
