That's 'cos they're ****wits! We have similar problems at RBoS. We use
Dell desktops as standard (about 16,000 of 'em!), and the service
contract is with Siemens. Talk about thickos.................

Spread the word then and get Swim's firm in - it's called Atos Origin
this week......

(You might find a Krell 'anything' or, better yet, a VSA-AX10Ai-S on
your
doorstep if you could swing it....... ;-)

Since when did "precision analogue electronics engineers" hold such sway
in a bank?


Oh, don't worry Tat - he don't!!


True enough. Hey, you finally got something right!!!

He works in the Print Room (clearing paper
jams and shredding misprinted statements or summat?) - the only
'electronic'
work he gets to do is 're-route' electrins occasionally - ie move an
extension lead when some big, scary bird tells him to!


Nope, union rules - not allowed to touch the scary mains stuff!

Mostly, I just find better ways of squeezin' out 6 million envelopes a
week - we have like *thousands* of big scary birds with big wet
tongues to lick the stamps!

(That and keep the
coffee machine topped up and wiped down...)


Nah, the big scary birds from the next office do that, 'cos they use
our machine right now, since we've got the builders in.

Still it's a lot more 'comfy' than being a Trolley Dolly, I suppose.....
:-)


True enough, according to me ol' pal Christine, a Finnish trolley
dolley who, like so many others, doesn't work for British Midland
anymore.............

Sorry, had to get a Star Wars reference in there ... I got my DVD
trilogy
on the weekend and can feel a marathon session coming up!


Oooh! Natalie Portman's bottle - very nice too! (She's turned out nice
since
Leon!! :-)


Aw, you were doing so well for a while! Wrong again, she's not in any
of those ones.




Well, I wouldn't really know - Star Wars was refreshingly different a
quarter of a century ago, I find it a bit puerile for my tastes now.....

The main problem with these old Nagras is indeed that they are battery
powered *only*, with no provision for a mains feed even if you're not
'on location'. Of course, not a really serious problem for a bloke and
his Black&Decker....... :-)

Which model, Stewart? I didn't really get into location work until after
the days of Nagras, but the ones we used for transcription purposes had
an
external mains power pack. They might well all have been IV Series,
though.

'Fraid not, it's an old Model III. And of course, no match for a man
and his laptop today!


I'm not so sure... they have their advantages. I've heard a recording of
a Nagra being dropped off a car park roof, and it kept speed when it hit
the pavement. That recording has a fair bit of dynamic range, as you'd
expect (it goes sort of sssshhhhhBANG and then it kept going). They were
built to last.

Somehow I doubt the average ProTools rig would fair as well under the
circumstances :-)


That is the reason I hang on to it. It's not a great performer by
modern standards, but it's a superb piece of precision engineering,
and just beautiful to look at - kinda like my GyroDec!



Woah! Truly? (I guess it takes all sorts....!!)

You would need something a bit bigger than a 845 to take advantage of
3k, 833 maybe...

Nagras all look pretty much the same, anyway!

Maybe, but I wanted to see *your* one - know what I mean? :-)

Stewart mentioned to me that he had a Nagra R2R in email yonks back..
unprovoked. Reckon he does own one if that's your line of enquiry ;-)



No probs - he emailed a copy of it straight to me and very nice it is too.
I
asked for a pic for a number of reasons:

Yes, to prove he wasn't just bull****timg.
Actually see it out of genuine interest.
Throwing him a stick to fetch.


LOL!

Good one ;-)

Encourage 'Show N Tell' activity in this ng.



BTW Keith, I found a bunch of emails my spamfilter ate.. including one
from you with a Värttinä track attached (" Some MoR music for
you.." 15/7). Apologies if that disappeared into the void! Will be
checking out these rogues shortly...



Go on, I don't recognise "Two Librans" - who are you really? (Email me
direct if you prefer to stay incognito! ;-)


Oops.. changed my name a few times already :-S



Is the tax man after you?? :-)

Yes, you're absolutely right - wouldn't be much more than about 1 - 1,5kV
would it? (He would need wet hands to be certain of getting the job done!)

Try this one:

So why does every amplifier on the planet do more than just make the
sound louder?


None of mine do - at least within the AF band...


Just 'cos you can't hear it doesn't mean it isn't doing it.


I knew that would be your pathetic wriggle. Are you joining the
'measurements are everything' viewpoint, then?

These just let you *approach* the limits of the laws of physics, but I
canna change them, cap'n! In extremis, the A6 will always be an
understeery pig, and I do have a tendency to find myself in extremis

wifey's TT back into my barge.........

Nothing to do with me, it's basic definition of what an amplifier
should do - *just* amplify.


But all amplifiers do just that, they amplify. Who says they shouldn't
do additional duties? You?


Anyone who doesn't want a tone control *permanently* switched into his
system.

Surely that depends on your definition of "bad" doesn't it?

It's a simple definition - if what comes out of an amplifier is not a
larger but otherwise identical version of what went in, then it's a
bad amplfier. Not a difficult concept - it's called high fidelity.

And if it was designed that way?

Then the designer designed a bad amplfier. It happens - mostly at very
inflated prices.

No, he designed an amplifier to do a specific job. When will you get
over your arrogance that presupposes that if you think it's bad then
that's what it is?


Nothing to do with me, it's basic definition of what an amplifier
should do - *just* amplify.

To me 'bad' is if it doesn't do the job it is intended for.

A Rover City does the job it was intended for - it's still a bad car!

How can it be bad if it does the job?


It does it very badly - kinda like a 2A3 amplifier............



Nice try Pinky, but it doesn't work like that - *I* throw the sticks, *you*
run after them and fetch them OK?


Nah, I just like to play with your subspecies for a while, until you
run out of sidesteps. Your little rodent friend claims to be
domesticated, but acts more like a lemming!

Now, did I (or did I not) see a little mention that you were tempted to toss
a little triode amp together yourself or was it just another 'brainfart' of
yours???

(The ****'s bound to go for summat with 845s, with 100W output and about

Correct - a push-pull 845 design was *exactly* what I had in mind,
although about 60-70 watts seems a little kinder to the output
devices, and you're clearly not informed about the B+ rail
requirements. Make your hair curl if you get careless though.....

The point was, after all, to prove that even a simple valve design
*can* be made linear if you know what you're doing! Essentially, a
Nagra amp at asensible price. It will of course sound just like my
Krell, or my Audiolab 8000P, or a Yamaha AX-592, but that's not a bad
thing, just an extravagance.

Not so linear as the 845, and I'm much to old to be *that* bold! There
are old engineers, and bold engineers.....................
