considering that ( hopefully) current going through one Jfet is having to go nowhere but other Jfet , that means that you're having 1A5 through both Jfets,and there are no more than these two outputs per channel , so that's 1A5 per channel

Yes, I showed several more versions, degenerating the input stage, the
output stage, and your variable arrangement, crediting the discussion on this
thread for the last.

Nelson: Any comment on modulating the "spare" primary winding as shown and discussed in these posts? F6 Amplifier F6 Amplifier.

variable arrangement , known as Zen Amount Pot , originated from Generg (playing with Babelfish J2 , or some other derivative ; can't be sure - our personal correspondence is sorta hysteric in organization ) and it's documented somewhere in some thread ; I was there with him only to mess things , as usual

that public thread was maybe ACA , maybe not .

lhquam made more than lion's share of investigating multiple combinations of two ZEPs together , in F6 .

buzzforb introduced it here :

ZM, Would pot across top Rs with center pin feeding cap give some adjustability of the output and THD performance?

The Mystery Man came over
An' he said: "I'm outa-site!"
He said, for a nominal service charge,
I could reach nervonna t'nite
If I was ready, willing 'n able
To pay him his regular fee
He would drop all the rest of
his pressing affairs
And devote His Attention to me
But I said . . .
Look here brother,
Who you jivin' with that Cosmik Debris?
(Now who you jivin' with that Cosmik Debris?)
Look here brother,
Don't you waste your time on me

The Mystery Man got nervous
An' he fidget around a bit
He reached in the pocket of his Mystery Robe
An' he whipped out a shaving kit
Now, I thought it was a razor
An' a can of foamin' goo
But he told me right then when
the top popped open
There was nothin' his box won't do
With the oil of Afro-dytee
An' the dust of the Grand Wazoo
He said:
"You might not believe this,
little fella, but it'll cure
your Asthma too!"
An' I said . . .
Look here brother,
Who you jivin' with that Cosmik Debris?
(Now what kind of a geroo are you anyway?)
Look here brother,
Don't you waste your time on me waste yer time . . .

I've got troubles of my own, I said
An' you can't help me out
So take your meditations
an' your preparations
An' ram it up yer snout
"BUT I GOT A KRISTL BOL!", he said
An' held it to the light
So I snatched it
All away from him
An' I showed him how to do it right
I wrapped a newspaper 'round my head
So I'd look like I was Deep
I said some Mumbo Jumbos then
An' told him he was goin' to sleep
I robbed his rings
An' pocket watch
An' everything else I found
I had that sucker hypnotized
He couldn't even make a sound
I proceeded to tell him his future then
As long as he was hanging around,
I said
"The price of meat has just gone up
An' yer ol' lady has just gone down . . . "
Look here brother,
Who you jivin' with that Cosmik Debris?
(Now is that a real poncho or is
that a Sears poncho?)
Don't you know,
You could make more money as a butcher,
So don't you waste your time on me
(Don't waste it, don't waste
your time on me . . . )
Ohm shonty, ohm shonty, ohm shonty-ohm
