Sorry,  But this does not explain anything. This is purely a subjective
explanation (which I am not denying that Chief_Billy experienced). What does
it mean to be "tighter" or "more soulful"? Is it the frequency response? Is
the it impulse response of the output stage? Is it the non-ideal behavior of
a resistor creating harmonics under high voltage swings? When you can relate
*an actual electrical phenomenon* to an adjective (i.e. tighter, more
soulful, etc..) and then explain how a different (plate voltage, capacitor,
resistor, output transformer, etc) affect that phenomenon then you will have
a modicum of credibility. In the meantime, you have no more credibility than
a 16 year old stoner who flips burgers for minimum wage.

And by the way Ether and Jim, exactly what are *your* credentials?

To adam79,

?Forget Jim's advice regarding B+ voltages. Unless an amp is out of
spec,
the sonic effect of the plates voltages is minute at most.

John:

When I reduced the HT (B+) voltage from the rectifier in my JTM45-
clone from 440 to 410 (which also reduced all other
DC voltages proportionately), it had a significant and, IMO, positive
effect on the tone and 'feel' of the amp. At 440 the amp was
'tighter',
but at the lower voltage the tone is more 'soulful', and the amp feels
a little spongier. Volume change is insignificant.

You just hit the nail on the head. John Mastrangelo, take note.

Y'know -

If there's anything I can't stand, it's fucking snobs.  Especially
the academic type, who screech about their credentials and
wave their goddamn sheepskins in everyone's faces.  *** you,
college boy.  I don't need to squirt math out of every orifice I
possess to be able to get good tone out of a guitar amp.
The dude took his plate voltage down and he liked the
result.  You gonna argue with him about what he hears?
One thing is for sure - with less voltage on the output
stage, the amp will clip at a lower power level.  When driven
hard, this will translate *directly* to output stage compression.
And compression, as most musicians know, is fucking
magic.  Santana built a career on it.  So next time you
get your undies in a bunch over someone's "credibility,"
you just remember that Leo Fender (radio/TV repairman)
and Jim Marshall (drummer) didn't have any letters after
their names.  And as far as I go, you'll find my "credentials"
in liner notes, on the radio, the Clapton tour, etc.  The
conclusion is inescapable - I FOOLED 'EM ALL into
hearing what they did not hear.  I dazzled 'em with math
and "credentials."  ***** credentials.  *Ward Churchill*
has credentials.  'Nuff said.

I'ts not often you'll find me agreeing with Willie, but I sho' 'nuff
do here.

I hate it when you agree with me.

I sentence myself to five solid hours of Hammond time, starting in a half hour.
That'll learn me.

Nice try, Willie, but you're not getting off that easy.  I'm thinking
8 years of Hillary will be a more appropriate penance.

Enjoy!

Ain't gonna happen.  You heard it from me first.  You *will* remember - either way.  ;-)

As to which ludicrously overfunded, lying bullshitter politician gets
installed as the govt's. mouthpiece to the world, who gives a ***?
Wake me up on that one when the running platform is about overhauling
the U.S. taxcode- something meaningful with real traction. Religion?
bull***. There's nothing for *any* of these yakking faces to discuss
that hasn't already been debated in some Jr. High student council
election.

If AGA stayed on amps, gear, music etc., DURING an election year it'd
prove to be a great barometer on the emptiness
of this election. The ONLY great news for Americans is that the
jerkoff from Texas becomes a footnote this year. :-)
