It is probably true that transistors always color (that means distort) the output slightly differently than tubes, but you and I with our ~60 year old ears won't hear it where *maybe* a 20 year old ...

Q: What is the difference between a hybrid amplifier and a tube amplifier? I have seen both advertised, and both seem to use tubes. Is there any difference? — B.P., Youngstown, Ohio A: Tube amplifiers ...

Did you know that the first half of the 20th century was dominated by vacuum tubes? Be it radio, television, telephone networks or computers, vacuum tubes were the basic component for all electronics.

PISCATAWAY, N.J. — Before there was the transistor, there was the tube. Lots of them. Televisions, radios — if it was electronic, it had a tube in it. Then, in the 1950s and 60s, transistors ...

Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the transistor age and the era of modern computing.
