If the Fitzwilliam you're online with is the one in Cambridge, my
favourite small art gallery, I'll give you a call the next time I speak
or dine there, and we'll have a drink or lunch or something.

Andre Jute
Thank you Andre, no its not that one although I have played classical
symphonic music in Cambridge, (its concert hall, I think its West Road).


Sure is, here

http://www.mus.cam.ac.uk/

and here

http://www.westroad.org/

Not a bad sounding place at all. Performed there myself once and my
middle daughter was in Mozart's requiem there last year)

You might actually find my fitzwilliam link equally interesting if you
care to email me and I can then send you some info.
Drink or lunch in Cambridge, most enticing, I wonder if that basement
restaurant is still in business.

Which one might that be the one on the corner of Bene't St and Kings
parade?..

I am in Stamford Lincolnshire, equally
nice but smaller. See www.stamford.co.uk.

So it is..

Kind regards and apologies to all for the personal details.

Thank you Tony, I only played there once and had a lot of trouble
finding it and parking.

I really enjoyed that concert and the venue, hope they have me back
sometime.

I think so, I hope its still in business as it gave wonderful value and
its prices were so reasonable.

Wish we had a concert hall though we do have outdoor Shakespeare at
Tolethorpe Hall every Summer.

snip parts about dying so easily and unoticed on desert islands.....


My fav amps, Nestorovic Labs Alpha One's, wished I'd never sold them.

I never heard of those. Tubed?
Yep Mono's
2 x 6KD6, 1 x 6CG7, 5 x 6JD8 and about 120W in 4 & 8 if I remembered
correctly. Milo Nestorovic was a Mack designer before doing his own thing.
6KD6 I think were originally TV scan tubes, right??

My RCA book says the 6KD6 is a beam power tube, Pda = 33 watts, so not bad,
Ra = 6k, gm = 14mA/V at Ea = 150V, Eg2 = 110V, and Ia = 120mA,
so it seems like it would be a good bottle for a low voltage supply of say
around 250V for PP.
120 watts would be flogging hell out of them, mainly class B, like
EAR509, with PL509 tubes also rated for Pda = 35 watts, but Tim deP got
100 watts... I measured 120, and they sounded worse than my 6CM5 25 watt triode
amps with
only 12 db global NFB, and crummy junk box parts I was given.

The 6KD6 are probably are not very linear like PL509, and triode strapping may
not work very well.
Only a few line output tets work ok in triode, my fav is 6CM5, EL36; these can
sound very nice.
Also the 6FW5, which is exactly like a 6CM5 electronically, but which has no
top cap
like the 6CM5 is an excellent tube triode connected, and it looks reallt neat.
There must be boatloads of 6FW5 hanging around in the US.

I am using a 25 watt 6CM5 PP amp in the hot weather here and its good.

The input tubes are all 6CG7; these are the same electronically as 6SN7.
I have AWV or miniwatt made in Oz samples, long plates, very nice.,
Siemans NOS 6CG7 are probably *the best* sounding signal triode of all time.

Originally designed as a TV sweep tube though I suppose that doesn't say too
much about their linearity. Mile Nestorovic designed many of the early
MacIntosh amplifiers which still seem to have a following. I understand it
was balanced from end to end so that could have had something to do with it.

120 watts would be flogging hell out of them,

Yes, used to get cherry red anodes during sustained & very loud passages on
a 4 ohm load, so OP tubes didn't last too long like that. But great sounding
amp IMO, it did most things right to my ears.

mainly class B, like
EAR509, with PL509 tubes also rated for Pda = 35 watts, but Tim deP got

I've also heard that the 807 makes a very fine sounding amp. Any experience
with those? I know in my early days they were used a lot for RF output and
driver / modulator tubes.

no
top cap

Expect it gets even hotter inside with your mammoth he-man tube amps running
;-)

Agreed, the Siemens 6CG7 is a fine sounding tube.

Most posters on these two conferences are senior audiophiles; almost by
definition they have more than one amp, and sweet memories of perhaps
many more they have parted from. Here's a tough question:

Suppose you can take only one amp with you to a desert island, which
would it be? (To make it easy, we'll assume your record collection, a
source and speakers are waiting for you, and the island is plugged in
to the universal mains electricity.) Why would it be that particular
amp?

Try to keep it clean, fellows.

Andre Jute

Well, if I was to be on a desert island, I would have to assume that spares
are repairs would be unavailable. Therefore, I wouldn't take a tube amp. It
would have to be something well engineered, giving no trouble, and reliable.
The Quad 405 comes first to mind, but a better more modern incarnation
might be the 909. However, if I was to be able to choose the entire system,
I would always go for active 'speakers, Meridian particularly.

Hi Andre,

On first tought, the EL34SET I once built.

It is amazing how many experienced audiophiles have a soft spot for the
EL34. Sometimes I think that a liking for the EL34 marks the dividing
line between real audiophiles and the rest...

Why would it be that particular amp?

"Because it sings." (human voices, stringed
instruments, orchestra, small jazz combos).

On second thought, I would chose my PCL84
trioded PP headphone amp with my HD595
Sennheiser headphones. See:

http://www.tubes.mynetcologne.de/roe...pcl84pp_e.html

Why would it be that particular amp?

"Because it is much more versatile with
all program material, if I get bored with
voices, stringed instruments, and so on."

Difficult to become bored with the human voice. After the stack of
Gregorian Chant, suggested to me by talk here about horns and TWQP, I
shall play Russian polyphony, of which I was reminded by stumbling
across several discs when going to look for a Tchaikovsky disc on the
Auvidis Astree label by the Fitzwilliam Ensemble on hand of
correspondence in this thread with Derrick Fawsitt. The kneebone is
connected to the shoulderbone... That is the purpose of the
crossposting to likeminded groups, crossfertilization.

Tom

(Crossposts stripped)

I've put the crosspost to the ukrainians back, as they have been
contributing good stuff to this thread and deserve to read your remarks
on both the EL34 and PCL84. BTW, are there enough PCL84 out there for
it to be "rediscovered"? What was it used for originally?

The opposite of a correct statement is a false statement. But the
opposite of a profound truth may well be another profound truth.
- Niels Bohr

Let Bohr try to explain to an engineer, who after all works in the far,
far, far lower reaches of *applied* physics, that spurious precision
isn't precision, it is just spurious.

Mind you, the first time I saw this quote in your sig, I thought to
myself, How encouraging for the guys searching for the grand unified
theory, because the *opposite* profound truth must of necessity include
all the previous profound truths, which makes their task easier, as a
progression from what they already know. But on second thoughts, if I
were a thinker about that GUT, I would find Bohr depressing: the
"other" profound truth may easily that there is no GUT, only blind
chance or even a dice-throwing God, as I explained on RAO a few weeks
ago. Fortunately, I am not a theoretical physicist, so I can follow my
literary inclination and take Bohr as a straight man to cosmic irony,
and chuckle each time I see your sig.

I have found this thread fascinating -- and not just for the choices --
and very worthwhile. Thanks all.

Yeah, I too thought of the Quad 405 in my own answer to my question,
though for a different reason than reliability (which I just
assumed...). I in fact have a Quad 405 sitting to my left on the
printer tray of a computer table, where it is permanently installed as
my second amp with Quad 67 and Quad 34 pre-amp on top of the table,
whatever I happen to be playing it the moment, a habit left over from
when I constantly reviewed audio gear and recorded music and had to
have reliable gear instantly to hand. This is my original reply:

*****

My favourite speakers in all the world are first series Quad
electrostats, retroactively known as ESL57. The best amp to drive them
is my own T113 Triple Threat, which is a trioded EL34 Class A push pull

amp which can be operated with zero negative feedback; it has a switch
for triode, ultralinear and pentode operation.


The question will arise: Why does a guy with all kinds of exotic SET
amps and fancy PP tube amps choose the humble T113 Triple Threat? The
answer is really simple. It is the best sounding amp I ever designed
and built. It is a bonus that it also has enough power to be really
impressive (24W with the ultralinear mode switch turned) on any
conceivable speaker, and it has the delicacy in the triode mode to
bring out the best in the ESL57 with my favourite early music and
particularly vocals. In addition it has a quality that I prize very
highly in amps, and rarely find: it is not forward, not pushy, not
bright, not boomy--it is an amp you can listen to all day without
fatigue. My second and third choices would both be Quad amps, and
equally modest, the Quad II (PP KT66) and the Quad 405 Mk II (current
dumping solid state), and for precisely the same reason, that if a
single amp will have to see out the rest of my life, I don't want a
rude, forward, impertinent, opinionated amp, but a cultured bringer of
unadorned music.

Incidentally, my second choice for speakers would also be Quad, the
ESL63, and my third choice would be my own Lowther driven
Fidelio-adaptation bicor horns. For both speakers the amp choices would

be the same as for the ESL57, in the same order.

Whatever was built into the digital player that I fancied at that moment.
My

That is *so* cheap !

Also energy efficient and with a real possibility of extremely high
fidelity.
