[Raymond Koonce]

Hi RATs,

Hope you enjoyed your Sunday afternoon as much as I did, working on a PP
amp using 71A triodes for my office environment. I breadboarded one
channel and a PS for testing purposes and it sounds pretty good to me.
The PS is LCLCRC with 7Hy chokes and motor run caps for filtering. The
amp uses transformer input with some Newcomb microphone transformers.
They plug into a really odd 9-pin "octal" style socket (noctal?). The
volume control follows the secondary and the wiper feeds the grid of a
56 which is IT coupled to the grids of the 71As. The IT is a Hammond
unit and I'm not sure it's up to par (the price was OK). It's the 124B
version with a 49% nickel core. The 56 is biased with a 2.2K R bypassed
with 100uF. The 71As have separate CT filament transformers with the
CTs connected to 1.2K bypassed by 47uF. B+ is around 200V with 40mA
through the output tubes. That's about it, not much in there, really.
It has about 35dB gain at 1KHz, a little weak in the bass. I suspect
the IT. I can get about 2 watts out of it at mild clipping.

I may play around with some feedback to see what happens. Any
suggestions as to a good IT? The Hammonds don't seem to have the
bandwidth to support the low end.

Best regards,

Raymond

Reading ancient texts is meaningless unless you can figure out how to apply
their wisdom to your present context. Therefore, being grounded in the
present is an important part of the experience.

No, not really. I like building the old circuits. Some of them sound

Thanks, Arni, I feel inspired.

Audio is only up to date now because it wasn't, then. We
should all build SS amps because only by not-being can we
have an inkling of being. History is the fourth dimension,
after all.

You poor sod - everything *must* have meaning?

How about simple poetry? There will be times (albeit quite rare) that
I will read Aristophanes "The Frogs" in the original Greek (which I
can read but have forgotten for the most part how to translate) just
to hear the poetry of the Frogs singing...

No "application" there.

Much as I listen to tubes - poor, misbegotten, distorting things that
they are - they simply sound good to my ears, but in an entirely
different way as my SS equipment 'sounds good'. I have no illusions
whatsoever of their "fidelity", utility or quality... just that I
enjoy them is more than enough.

That you are so limited an individual to demand that your perspective
must be the only valid one for all to follow makes you the wretch, not
the rest of us who are able to enjoy things without necessarily
imparting great meaning or value to them. Our time is our own to spend
as we see fit without stone-ignorant creatures such as you yammering
over things you clearly cannot understand. And then drawing the
conclusion that because you do not understand, those things cannot be
worthwhile. Fox and grapes, as previously noted.

Who would claim that? Perhaps we have both - that one has steak in the
freezer does not make one averse to a simple bratwurst on occasion...

Most of us with any time in the audio hobby have more than one system
in place. I know of a great many SS system owners who have no tubes,
but I know of no Tube system owners that have no solid-state. It would
seem from the evidence that the self-limiting SS owners are more
ignorant of what is out there and how it migth sound than the tube
owners - based only on my own experience and anecdotal evidence.

Show of hands: Of those who participate here as *actual* Tube
hobbyists/designers/afficionados (as opposed to wannabes and
spoilers), how many of you also own and operate SS systems?

For myself to start out, active systems in active use (more than 2x
per week):

Tube: 2
SS: 4
(6 sets of speakers across the 6 systems above)

Available additional systems (inclusive of at least one source and
speakers) rarely or not used.

Tubes: 2
SS: 3
(3 *additional* sets of speakers shared across the 5 systems above).

Notes:

These systems are spread across two houses, so the summer-house
systems get used every day we are there, but not every day. Due to
distance, placement, use and security, both systems are solid-state.

Our main house has four active systems in three rooms. The library has
two active systems, one-each. The kitchen system is SS for obvious
reasons, the shop system is tube - and the shop system is constantly
changing.

It's a hobby - no great store is set by it other than simple
enjoyment.

For the record - there was never any "discussion" on your part. Just
your pontificating on what you don't understand and cannot imagine.
Which, in no small part, contributes to the general lack of respect
you command here or anywhere else in Usenet - also a matter of

You are muddying waters where you are neither wanted, nor do you have

Actually, he did not. He merely stated that the 71A is one of the most
linear of tubes. Not hardly the same thing - except in the mind of a
stone-ignorant jackass incapable of understanding what is actually
being discussed. Well, I must apologize - to the hooved jackass. They
are hardly so ignorant as you and seldom intrude where they are not
wanted. Whereas both of those traits are nearly your entire stock-in-

b) If one is designing a triode-based amplifier, one might do well by

Just to heap more mud on your pointy little head - what an distortion

relevance to what I enjoy doing and what my hobbys encompass or the
focus of my listening pleasure. Nor would I pretend that _anything_ I

anything, at all. But it gives me pleasure.

That nothing here or related to tubes appears to give you pleasure -
that you insist that all our "grapes" must be sour makes you the 'poor
sod'. Not those of us who can find enjoyment in such simple,
distorting, spavined little glass bits such as vacuum tubes. So, go
away. You have nothing to offer here, you don't understand what goes
on here, you cannot participate here in any meaningful way based on
your history past and recent - you are a waste of air, water, space

The good music obtained by the OP is due to the splendid
linearity of the 71A.

I agree with what you say though, and you said
for the most non-linear distortion, use solid state.

Its extraordinary distortion from SS, it isn't even linear in itself.

You forgot to mention that huge amounts of NFB are needed to
linearize the awful performance by SS.

Yes, ppl say I should do lotsa things, and some
say i should get ****ed.
Its illegal these days to think about sex once each 5 minutes, if you
are over 60, while dreaming about it all night long.
Its demeaning to wimmyn you know.

Anyway, line dancers think about sex each 2.5 minutes, lasting about 30
seconds,
thus leaving 120 seconds to co-ordinate foot movements
to raucous music sung by Garth Brookes et all, before
another sex thought occurs.

The line dancers need to think very intensely about foot movements
( and the odd hip movement ) and because of their country
social orientation and having spent years alone on tractors or in lonely
country kitchens, their focusing efforts when dancing is exhausting,
thus diluting
the intensity of sex thoughts for the 20% of the time dancing.
They compensate for the complex social situation by forming
M-F-M-F-M-F conga lines which snake right down the town square,
and the only reason mass rape on the spot does not occur is that the M
participants cannot maintain a hard-on while line dancing,
and while remembering that the husband or boyfriend of the Ohio girl
your'e hangin' onta has a large shotgun in the rear of his F100 pick up
truck.

Country livin is all about titilation and denial,
with ever so few ppl ever actually being happy, and the C&W music lyrics
indicate how true it is for the folks out west.....

The all go west to get away from city livin, but they end up trapped
with themselves....

Never said any such thing. You seem to live in a world of imagination.

Not those of us who can
find enjoyment in such simple, distorting, spavined
little glass bits such as vacuum tubes.

Hey, whatever floats your boat!

So, go away.

Ummm, no! ;-)

snip yet another childish melt-down

The 71A is one of The Most linear triodes made.

No wonder it sounds well.

If you want the best possible nonlinear distortion
performance from an amp, go SS.

D'OH!!

And what if that is *not* the point, nor what we *want*?

Then enjoy!

BTW, I'm not the one who brought up amplifier linearity
as an issue. Patrick did.

The good music obtained by the OP is due to the splendid
linearity of the 71A.

I agree with what you say though, and you said
for the most non-linear distortion, use solid state.

Of course that isn't what I said, but enjoy your little melt-down.

Its extraordinary distortion from SS, it isn't even
linear in itself.

Have I ever said otherwise?

You forgot to mention that huge amounts of NFB are needed
to linearize the awful performance by SS.

It takes huge amounts of NFB to even run a car engine these days. People who
have phobias about NFB must live tortured lives.

Whether he is missing out on something better is
irrelevant, after all why restore a 1929 Blower Bentley
when you could buy a far more comfortable and better
performing modern car at a fraction of the cost?

Sentimentality

Other people's sentimentality - profit motive

People do all sorts of things, mostly pointless in the larger
scheme of things, simply because they enjoy it.

Why else would line dancing exist?

Social contact, exercise.

The are many ways to get that without looking a complete dork.

A lot of people aren't so pretentious that it would matter to them.

I. You have bull****ted here for years, twisting the truth like
plasticine.

2. You have NEVER EVER offered one single piece of constructive advice
to anyone using vacuum tubes
in any electronics.

3. There isn't any need for ppl to be phobic about NFB, and most here
ain't.
But because triode are so linear because of their in-built NFB, there
isn't
any need to add more if you allow for these facts in a given design.

4. Go away, you don't belong here.

All you would need for that would be a mirror and a tiny modicum of

I have plenty of mirrors, and for your purposes Peter, way too much insight,
personal and otherwise.

That would be your delusion. I would refer you to Matthew 7:3, King
James, were you to have any hope of understanding its meaning. Save
that the reference is poetic - and as an ancient text that you cannot
understand has no "relevance" in your case as stated in your prior
posts.

If you had any "insight" at all, you would understand that you have no
place here, that you are pretty much universally reviled here, and
that you will have no net effect here of any nature other than to give
some of us a chance to polish our invective. Sadly, as you do have
such trouble with the rules and forms of logic, the meaning of words
and the English Language in general, most of that is lost on you.

Repeat: you are a poor, sad, delusional sod. I think I might add
'ignorant' or 'obtuse' next time. But I think that 'delusional' covers
it pretty well for now.
