Title: How a Tube Works
Post by Lonely Raven on 02/14/20 at 15:41:11

I may have posted this before, but I was researching something and this popped up again, so I thought I'd share it.

I've always assumed that tubes worked by some sort of sorcery, black cats, spells, that kind of magic. Turning Lead into Gold, alchemy stuff.

Donnie,

I know this... the sound is inside the tube! If you crack the glass and let the sound out, the tube will never work again! Seems pretty magical to me.

Ok, music is contained inside tubes, electricity is smoke, and magnets attract and repel.
So what changes the music into smoke so that it can cause the magnets to attract and repel? There must be some sort of music to smoke converter.
Perhaps this is where the magic comes into the equation??
For some reason this reminds me of a Monty Python skit.

I've converted music into smoke more times than I care to admit. Last week it was an electrolytic capacitor in backwards - lots of smoke, a big bang, and a bad smell too.

Make sure you catch the smoke so it can be put back in, otherwise the cap will not work.

I learned from reading Glass Audio magazine many years ago that all passive or active electronic elements are actually "smoke containing devices," thence what once was music now being converted to "contained smoke."

So when you see smoke coming out of a tube or a transformer, you are actually watching the music escape.

I really like the old educational videos. They make it so easy to understand. It's also an interesting way to see history.
