Sound Quality Vs. Measurements

I had a chart published in about 1908 listing many ten's of semiconductor materials . I think 1880 was when Siemens produced selenium devises commercially ?

I read that a French engineer claimed to have perfected television in the 1880's using selenium cells . Some say Baird knew of this and added amplification . If I am right both worked by optical scanning ?

And it took until 1955 to build the first BJT. Guess they were not in a hurry as the tubes worked pretty well until they needed to send them to space.

The next step will be to utilize entanglement to eliminate cable distortions.
I am sure certain parties are already working in this (funded by the military of course, and they would have to shoot us if they told us how it works), and it will appear at your local snake oil merchant very soon. Probably involves room temperature near-superconductors (not to be confused with near-room temperature superconductors - very different stuff).

Yes, and they discovered the entanglement effects while trying to straighten up the wiring behind their stack of equipment.

It sounds like taking TV and fridge on camping. No, thank you, I pass. :)

A man on a beech saw beautiful lady, with legs growing almost from ears. He approached her and started talking to her, asking if she would like to spend some nice time with him. She asked, "What is your profession?" He said, "I am a machinist". She said, "Now imagine, you work with your machines, got tired, and one weekend went on a beech to relax, but see machines, machines, machines all around!" :D

It was my reply to dvv idea. :)

Not in my experience, I must say. Some of the best conversations I have ever had were done over shish kebab and ice cold beer, in an unassuming envirnoment, among people who felt that they were with friends.

Since that would not be a conference, audio would be talked about, but among other things as well, just as the feeling took the company. Just let it flow and play by ear, see how everybody feels and take it from there. If we should spend the day without even mentioning audio (MOST unlikely), so what, the idea is that everybody goes home happy.

Rest assured I would not pass up the opportunity to make a few comments about your truck, or SUV, or whatever. :D :D :D

Not to even mention your toobes. :p

Anyway, that's just a nice dream, you live where you live, and I'm still like 7,000 miles away, with lots of salty water in between. Any real chance I have of meeting in person people from this forum would be the UK members, I am hankering to hit London again, haven't been there since 1986, and I sorely want to go. You could even say I actually need to visit the UK again, although my visit to Scotland in 2009 helped a lot.
 
Each October we have meetings in San Francisco, called BAF. You are welcome! :)

BAF means, we are Burning Amplifiers in Flame, instead of coil for barbecue.

Thank you for the invitation, Wave.

I know about that meeting, a few friends have attended the last two.

However, the same old problem is still there - the sheer distance, which imposes stiff prices on it, from where I live. Given the current economic crisis, which is MUCH worse here than there as our starting point was already poor, the chances of my coming are practically nil. Local unemployment rate is well above 40%, average monthly salary is below $500, the rest you can piece together.

Sure, my Family, Inc. does better than that, but this year we have already spent quite a bit on the new car (about $20 grand), for our summer vacations (about $5 grand in total for son and us), and we are still trying to find employment for our son.

And it will get worse before it can get better.

If you were me, under the circumstances, would you tax the family budget with say $3 grand for what is essentially a fun trip? Plus the plane tickets?

So, sorry but I'll have to pass.
 
In 1999 in South Africa some British students went on excursion, for wine tasting; once one bus with students passed another, and drunk student decided to show them naked butt through the window.
... the whole country prayed for his life watching TV news. Medicine in SA was still great then, the guy that fell down from the window survived!

It is the miracle how drunk people survive falls from windows, including windows of buses, on freeways...

For the record, I have seen drunks on the streets of Stockholm, Paris, London, New York, you name it.

Some of the other stunts shown I have never seen, nor am I keen to.

But people are people, and people will do all sorts of crazy things - everywhere.

Of course, it's a cliche of the country. Same walking on the wild side could be seen here localy too. Maybe on a more rare scale.

Speaking cliches, there are worst.
 
What is amazing, US is populated by emigrants from many different countries. But despite of that Hollywood use artificial cliches to picture foreign countries. For example, people often ask, "How did you live in Siberia, it is so cold there!" :D
Here are some typical pictures taken in Siberia I found in the Net:

If one wants to nitpick, then each and every country could be cliched.

In really large countries, such as USA, ever regional differences could be made big. For example, I have heard several Bostonians and New Yorkers say that California is not of this planet. Unfortunately, I never managed to get off the East Coast, so I haven't seen what they mean myself.

In 1992, I was on Taiwan. While their level of development was impressive, to say the least, I was amazed at how thin is the outer skin of civilization. My impression is that a power outage lasting say 3 days would bring it all back and the thin shell of civilization would crumble. It's still a very strong impression about the Chinese I have today.

Cliche has it that they have 5,000 years of civilization behing them, but nobody wonders exactly WHO had it all. Certainly not 99% of their population, which was too busy surving. Only some mandarins, rich enough to sit back and muse upon the world.

Just look at the photos Wave put up. To an average Westener, they must be something like a revelation, because Siberia is traditionally thought of a hell on earth, easy to get to, hard to leave. Admittedly, it was that too, but overall, it looks a lot different than the general public thinks.

On the other hand, some years ago, ex US Secretary of State Madeline Albright publically wondered whether Russia really thought Siberia was really only theirs? Remember, what is known about Siberia makes it easily the richest mineral and oil area in the world, bar none, and over 80% of Siberia has not been prospected yet.

If we were to cliche this, how would that make USA look?

Personally, I like to streer clear of any cliches, I find they have a grain of truth in them, but are mostly false and inaccurate.
 
Yea, but here we invented the phrase "Hey Buba, hold my beer and watch this!" What does that translate to in Serbian?

Honestly, I don't know what the phrase means, but translating popular sayings and wisdom always boils down to translating idioms. Hard to do, always a challenge, but more often than not, it can be done.

I have been a member of Serbian Translator's Association since 1979, and have served on several boards of the association, so I think I have earned the right to say this - good translation depends much on the translator's own intellectual and educational level, and on his/her imagination. In essence, we translate the meaning, not the words per se, unless it's some form of technical documentation, in which case there's no fooling around, you either know the jargon or you don't.

The above sentence is easy to translate on its surface meaning: Burazeru, drži mi pivo i gledaj ovo. Or, in Serbian Cyrrilic: Буразеру, држи ми пиво и гледај ово.

But I am not sure it carries across the real underlying meaning, frankly, I have never heard the expression before.

Many years ago, I mused over translating "slew rate" properly. Not that I had to, any half baked electrical engineer will know what it means in its English form, but as a challenge. I mused over it for a full week before I came up with a roughly equivalent phrase in Serbian. Never tried to launch it.

Hi Wave . I was told to do the whole Trans Siberian Railroad trip is less than $200 . I offered to take some Slovakian friends on it if they bought the food and Vodka . 8 days . I planned for the coldest period . Your pictures convinced me although I might have to revise the time of year . My boss was furious as he thought I was making false promises to these young lads . No , the thing about buying the food was the bargain and far less than a DVV summer vacation . The lads offered me a tip to Chernobyl which was about 100 km , the boss firmly said no . It is now banned as the sate wasn't getting a cut , not safety !

We were talking about when transistors took over . I would say 1967 is my best guess . I think the Apollo project was partly responsible . Like lighting a fire the interest doesn't need space to fuel it now .

Technical advice if possible . Would adding a capacitance multiplier ( single MOS FET , in place of PSU choke ) to a SE tube amp increase second harmonic distortion ? It looks to me it does . I said to myself it is an amplifier , it must being doing something ? I could try a Darlington made up of TV transistors as I suspect they would be very linear as a current amp .
