Cool article, thanks for posting Milkman. Let's hope we continue to see improvements in New New Stock.

well it'd be nice to see the art of cathode chemistry return!

Imagine being able to rely on new production tubes - what a wonderful world this would be

Alchemy!

Indeed! It is kind of hit and miss now but I'm just glad we have what we do. I hope that increasing demand will spur interest and investment in revisiting The Olde Ways.

No glow? They'll never replace a pair of 807s.

"But transistors weren't better in all respects. Electrons move more slowly in a solid than in a vacuum, which means transistors are generally slower than vacuum tubes; as a result, computing isn't as quick as it could be."

Wrong answer. Thanks for playing. We have some lovely parting gifts for you backstage. Buh-bye...

That's why really high speed circuits don't use 45nm or less MOSFET technology, they use vacuum tubes, because everyone knows that parasitic capacitance doesn't matter and electrons move faster in a vacuum...

Remind me not to join AAAS.

Is that because of the crystal lettuce?

LOL light travels slower through butter. I have an idea for a time machine that tastes good on a biscuit. Yum, again.

Wrong answer? Which answer is wrong? Electron drift and mobility is less in a semiconductor compared to a vacuum. Manily due to a reduction of scattering due to the lower probability of collisions in a vacuum. Electrons can move faster in a vacuum - this is a fact. How this nano-tube might impact computing speed is a different question. It actually could increase speed at the expense of power, which is a tradeoff that cannot be ignored. In general, I am not so quick to dismiss this idea.

Parasitic capacitance is always an issue in high speed circuits, but this technology isn't inherently high capacitance IMO.

It's the false conclusion "Electrons move more slowly in a solid than in a vacuum, which means transistors are generally slower than vacuum tubes." Yes, electrons move faster in a vacuum than in a solid, but that does not make transistors slower.

What I want to know is why phosphorus-doped silicon is immune to radiation...

all I know is that its a race to see which one of our amps makes it to outer space first!

I've got an amp which is being unloaded on the Int'l Space Station as we speak It is shielded throughout with gold foil otherwise RF emissions from our galaxy's Black Hole cause Britney Spears to be played through the amp when idling with the guitar volume turned down. Nobody likes that. The tubes have been cryo-treated by placing them in the vacuum of space for a while. The caps are also gold foil and polyester. The amp weighs 10kg and cost $10M. But what a tone!

Just imagine, if that quote from back then started all this and was quoted in the scientific paper.

"I really got the idea, when I saw this video on YouTube..."

Come on guys, think about the fragile harmonics!
