No shame at all.

My 'audio learning curve' is not much longer than my subscription to this
group and I'm here to learn - never claimed any different and never made a
secret of it.

The real shame is that this group's not really up to it - all one can expect
here is an endless torrent of the same, meaningless, bigotted yap from a
very small minority (1.5 clowns) who have nothing useful to offer other than
pounce on every post and try to turn it into some sort of knob-waving
session. The biggest mystery to me is why do I continue to subscribe when,
even as I type, I have better things to do??? (A bit different in the
evening when I'm usually listening to music at the same time and I'm in the
mood for a litle mischief.... :-)

Thankfully, there are a multitude of seriously interesting and informative
sites on the Web like this one:

http://www.nutshellhifi.com/triode1.html

Read it carefully and you might learn something.

You will also see "Putting it less kindly, the good engineers went into the
commercial, instrumentation, and military sectors, while the not-so-good
engineers went into the high-fidelity business." Where does that leave
'self-styled wannabees' that are not 'engineers' at all, but work in places
like banks, sweeping up or whatever???

(Out of interest, my brother is a real engineer who has worked in the
aerospace industry all his life - BAC/BAe and currently Matra Marconi......)

Read it carefully and you might learn something.

If you'll recall, my own suggestion for a *good* valve amp is a class
A triode P-P design.................

Of course, most of Olson's guff regarding actual *sound quality* in
that article is utter ********, since *any* decent SS power amp will
simply sound like its source component. All Olson is trying to do is
to get *back* to that sonic transparency under the handicap of using
valve technology. A fine aim for the curious hobbyist, but pointless
if you're just after a top-quality amplifier.

You will also see "Putting it less kindly, the good engineers went into the
commercial, instrumentation, and military sectors, while the not-so-good
engineers went into the high-fidelity business."

Thjat is indeed a very true statement, although the 'mainstream'
companies like Harman-Kardon, Meridian, Philips and Sony do have some
excellent engineers. I'm a military instrumentation guy myself.

Where does that leave
'self-styled wannabees' that are not 'engineers' at all, but work in places
like banks, sweeping up or whatever???

Ever wonder how Banks get all your statements and letters sorted out?
It's not a million clerks with quill pens, y'know! Well, maybe at
Coutts &Co................

We've just upgraded *some* of our kit at the shed where I work, cost
more than 7 million squids, paid for by you guys! :-)

IIRC, the driver was at the fireplace end, the chimney being used as a
B&W style tapered transmission line, rather than a horn. But it was a
long time ago, late '60s or early '70s I think.

Worked well with glass-fibre loft insulation stuffed up the chimney to
damp the resonances. A good location for a proper bass woofer if you
still happen to have the right chimney.

I've even got the ideal Goodmans Audiom 81 to use for it to keep it all
early-70s style! (As well as four Goodmans 301s for when I finally can
afford to buy a barn!)

The HS was neither nasty nor little! It was only displaced by the
appearance of the all-conquering Audi Quattro, and both HS and HSR
versions are now valuable classics. Unfortunately, a lot of standard
'Shoveits' were Chavised with big wheels and plastic 'droopsnoot'
noses - indeed, they were direct ancestors of the bright orange Corsas
with DTM wings and dustbin exhausts which plague our streets today....

I'm seeing quite a few 350Zs around, and a small car with a big engine
and rear drive is starting to bring back fond memories.....

You probably are - but what I said was that I was considering

I was at the National Vintage Communications Fair at the NEC today. One
chap had a pair of 833 triodes for sale at only £10 each. Now if you
were prepared to have the OPTs made (about 12K primary Z at 200mA dc
should do) and you build the 2kV supply then you could have a stereo SE
triode amp to beat the Japanese monsters.

But wouldn't it be nicer to build a naughty amp, and have some fun?

Heaven help us when we all subscrbe to the 'flat response curve is best'
argument.
I'd much rather rely on selecting the amp that my ears enjoy most.

Then again, maybe I'm a fool . . .albeit a happy one.

You probably are - but what I said was that I was considering
designing and building a triode amp. I most certainly did *not* say a
single-ended amp, since they're fundamentally incompetent, and my

technically challenged by using valves........


Well, come on then - cut the cackle and get stuck in! Do what new Geoff says
and 'have some fun'! (Who knows, if you build it it, you might even like

In any case, you should be able to make a few ackers on it if you didn't
want to keep it - who here could resist a 'Pinky Special'?? Feck, you could
even spray it pink and get a real 'rosy glow'....!! :-)

I was at the National Vintage Communications Fair at the NEC today. One
chap had a pair of 833 triodes for sale at only £10 each. Now if you
were prepared to have the OPTs made (about 12K primary Z at 200mA dc
should do) and you build the 2kV supply then you could have a stereo SE
triode amp to beat the Japanese monsters.

Which part of 'they're fundamentally incompetent' did you fail to
understand?..................

Also, why would one save a few quid by buying those triodes, when a
pair of suitable wideband output trannies would cost the best part of
a grand? That's the *other* reason that SETAs are a bad idea, the
trannies have to be absolutely *huge* because of the high level of DC
current.

But wouldn't it be nicer to build a naughty amp, and have some fun?

I was contemplating something with 1100 volt power rails - that's
pretty naughty! And we all know that you have the best fun when your
partner is naughty, but very very good...................... :-)

Heaven help us when we all subscrbe to the 'flat response curve is best'
argument.

It's called 'high fidelity', an interesting concept you might have
heard of at some time.............

I'd much rather rely on selecting the amp that my ears enjoy most.

Then again, maybe I'm a fool . . .albeit a happy one.

No comment................ :-)

Busy rebuilding a bedroom right now, so all the hi-fi stuff's on the
back burner. I'll probably do the 'big sub' first, as it will be a
useful addition, rather than just a curious toy.......

I had a look at the anode curves on the Duncanamps site. As far as I
can see, there's no way to get any sort of linearity out of one of them
single ended. A pair in class-B P-P must have made a scary PA amp in
the old days, but certainly not one on its own.

An OPT would cost a fortune, I paid enough to Sowter to have a couple of
SE OPTs custom wound for my DA100 triodes, and they're only 900V at
90mA.

I actually like properly designed SET amps (using proper triodes like
845's or DA100's of course, not weedy little 300Bs), but I would NEVER
claim that they are high fidelity!

What the triodes or the transformers :-)

The DA100 is a wonderful looking bottle, about 7" tall. It's one of a
handful of valves with a very strange square 4-pin base. Once you've
seen one you won't fail to recognise another one. They are worth silly
money nowadays. I sold 3 rather rough ones on Ebay a year ago, one had a
broken pin and they still fetched over £500 for the three.

I still have four. Two for the amps, and two as spares.

Arrrrrrrrrrrrrrrrrrrrrrgggggggggggghhhhhhhhhhhhhhh hhh!!!!!!!!!!!!!!

Threw a load of them out about 6 years ago!. Never thought anyone would
ever need them again!!!...
