I am still waiting for Murano-glass tubes... they are said to add more, ahem, color, to the sound

Great video Myles. As much art as science in the making of those beauties.

Impressive. Really hand made. I have to get an amplifier using 845's!

I am always impressed that they (well some tubes) can hold their tolerances sample to sample as well as they do.

It is really fascinating. I think that most of their constancy is due to geometrical symmetry of the tube around the flat cathode. Most of the small imbalances in the electrical characteristics due to off-center placement cancel when they are summed for both sides. But we can easily admit, that as this effects are not totally linear with space, more perfect tubes will have better characteristic curves. It is really an wonderful device!

Hello, Myles. A friend of mine passed this video on to me and it's right up the alley with this thread. It's an old school film, thought you might enjoy it. [33 minutes long, FYI so reserve some time to watch it in its entirety]
