Overtubing? Danger?


I like the sound of tube amps. When I was a kid, my family had one of the huge music consoles and I was always in amazement when the back was removed for maintenance and a whole city of tubes was revealed. Plus, it sounded fat and rich.

Today, I am trying to recapture that sound, but I wonder. What does a signal from a CD transport, with tubes, sent to a pre-amp, with tubes, sending a signal to an amp, with tubes due to the sound? Is more tube better or is it overkill?

Tubes and transistors all have the same function in stereo, to amplify the signal. And just like everything on earth, nothing is ideal. If you look at any transistor curve (I-V), you will see the linear and saturation region. Unlike a CMOS in your computer where it only operates in high or low, transistor in stereo actually operates in all regions and often in the non-linear region. Tubes are the same but operates in different current range and on a different curve.

So is too much tube a bad thing? Can one say too many transistors is a bad thing? Neither is bad and neither is good, it's what you like that matters. Nothing is close to live performance, but I do find tubes to be closer than transistors and the more the closer.

As for transistors to get us up to the moon and fly across the ocean, tubes can do that as well. We can use tubes to build a space shuttle, it will be quite a bit bigger because each tube takes up so much more real estate where you can pack millions of transistors into one sqaure cm.

An engineer in AMD that looks at transistor everyday but goes home and listen to tubes.
