I just saw this on How It's Made, and I thought I'd share it with you guys. Pretty neat.
... that was awesome...
and what a fantastic CRAFT! I mean Almost purely all hand made... and I love that they "pair" tubes together! I love how involved people are to the process of tubes! A ss is made my machine, but MAN makes the Tube ;3
Pairing tubes helps, especially in A/B and class B operations. Matching improves sonic accuracy.
I had no idea there was so much hands on glass work. No wonder these things can be mass manufactured by machines.
It is ancient when you consider that tube technology came around the turn of the 20th century. Although improvements to design of tubes and tube circuits still continues in the audio world.
Yep but look at that old mcintosh 275 who has 0.5% of THD, the difference is huge, I don't see the point of getting a 16K amp to have so much distortion, even if it's euphonic, you can add distortion or "tube sound" yourself.
When you compare ONE triode tube to ONE Bipolar Junction Transistor, actually the tube is MORE linear.
Solid state line level amps may have 30 transistors and a lot of feedback, an "equivalent" line level tube amp may have two triodes and very little feedback.
