[ARC5] Added 6F6 audio stage.

[David Stinson]

OK... I confess.  

I think I *do* understand why people chain-sawed extra 
audio stages into mil rigs, and I've already illustrated it,
but I will again because I'm a meany.

1.  A cool and lovely fall morning in Chicago, 1961, 
which is about to turn ugly.... very ugly.
Doofuss #1, with no understanding of the original circuit 
nor any inclination to find out about it, hooks-up an 8-ohm
speaker to a 4000-ohm output.  
*Surprise!*   He gets low audio.

2.  Doofuss #1:  "Why it's just like my buddy Clem said- 
them military engine-ears don't know nothin'!  I'm a 
Cornditional Class by God an' I know more than Marconi!"

3.  Out comes the chainsaw-
"Waaa-wub-wub-wub-wrrrrrrrrrrrrrrrrrrrr...."

4.  In goes some half-baked, upside-down "audio amplifier"
with 87% harmonic distortion and a junk-box output 
transformer which, by the way, *still* doesn't match 
the old speaker (including bonus moth holes)
taken from a junked Philco.

5.  The poor, mangled radio, instead of delivering .5 watts 
of nice, clean audio, now delivers 
.75 watts of nasty, distorted audio.  Such genius!  
In fact, Doofuss #1 is so proud of his "craftsmanship," 
he writes an article for CQ magazine, 
which publishes it to a waiting world.

6.  Doofuss 2, 3, 4 etc. read the short article-
which is so much easier than reading boring old texts about
how the stage was supposed to work-  and tell all their fellow 
Doofussi about the "wonderful modification improvements,"
who parrot it forevermore, Amen.

7.  For the next 5 generations 
(or until the supply of doomed radios runs out),
where ever soldering irons are heated,
from sea to shining sea,
if one listens in the wee morning hours,
one can hear:
"Waaa-wub-wub-wub-wrrrrrrrrrrrrrrrrrrrr!"

OK.... that's really what I think 
is behind the audio "improvements."  

But I don't think I'll write about it.
Because Doofuss-1286 and Doofuss-1342
will get mad and call me nasty names.
