THIS

(particularly when the 'clean' channel is up to 9 or 11 and starts to break up in that magical way that just preamp tubes can't possibly compete with)

And, in this case, little tiny dump trucks.

Didn't Asimov's positronic robot brains run on ultra-miniaturized tubes? If so, chalk up another prediction for ole' Isaac.

so maybe ipods will one day achieve superior sound quality by incorporating tiny vinyl records?

This, that, and thems up there.

There is nothing on Earth that sounds as delicious as tubes driven just over the edge of distortion.

Smaller vacuum tubes?! Bad idea!
I hate it when my vacuum's tube is too short and I can reach beneath the couch to suck up those stray popcorn kernels....

You and your new-fangled vacuum tubes. Everyone knows that old transistor radios have the sound audiophiles love.

I said, no, Geri, the heating is the muthafarkin'...spring! This one here as soon as you start turnin' over the engine, it's supposed to pull it back when the vacuum starts. When the vacuum starts, nothin' to do with farkin' heat. Vacuum!

Kustom has been doing marvelous things with their Defender line. Everything about them is great, except the name. Defender? Really?

So, let me see if I get this right. First, we go from computers that are stand alone beasts back to dumb terminals working off of servers, then we go back to vacuum tubes.

Does this mean that my pencil tie and fedora are back in style, too?

Another famous tube with a very high power handling capability:

www.thegreenhead.com


Back to TFA: This concept was ballyhooed back in 1990 (in the March, 1990 edition of Discover Magazine, to be exact.) They were hyping the same stuff: faster computers, radiation resistant hardware, etc. However, they were having trouble with electrons bouncing back off the plate and destroying the cathode (IIRC). Haven't heard a peep about it since, until now.

As a stereo geek, I thank you guitar players for keeping (foreign) tube production alive.

I'm currently using an HH Scott 233 integrated amp, but eventually I'm going to get my HH Scott LC-21 preamp and McIntosh MC30 power amp setup going. It's a fun hobby.

I have an TS-820 that was my first rig. I also bought an TS-830 but that one has been at the shop for a few months now. A couple of months ago I bough a Flex 3000, but I have not had the time to get it working the way that I want.

Favorited as a ham for Fark QSO Party purposes.

Of course. Still many, many surplus Nixie tubes available, Russia and Eastern Europe were producing them into the 80's in great quantity. AFAIK no one's been producing them since the 80's, but lots and lots of NOS (New, Old Stock) around for making neat stuff with.

Yeah, built a nixie clock back in '04 or so. The way my old apartment was setup you could see my work bench from the front door. I had ordered tubes from some guy in Russia, when the mailman came to the door with a package covered in cyrillic, he notice a whole bunch of wires and electronic bits around a nixie clock I had not built a case for yet. He looked real worried until I said "No, no, it's a clock. Clocks count up, bombs count down."
