    Thank you for the explanation.
    Can I get a cheap amplifier for my small living room or are they only for the "audiophiles" with deep pockets?

    It is very similar to the way digital and film handle highlights.

    The word 'distortion', though technically correct, unfortunately conjurs up the idea of a harsh rattly sound to the layman. Distortion really refers to any deviation from a linear response. In valve/tube terms, it is a slight deviation which can make it more pleasing to listen to..... And they look cool too!

    I am not sure the analogy holds: it doesn't take much technology to make an audio/receiving vacuum tube; the appeal of vacuum audio isn't performance but rather the lack thereof - the cyanotype of the electronics world, as it were.

    I suspect it is easier to make a light sensitive emulsion. Here is an example of a guy that makes vacuum tubes. Seems like a lot of equipment is needed compared to home-made film. http://dailymotion.alice.it/video/x3...pe-triode_tech

    Thank God for the Soviet Union.

    And having tried to home-make film, I figured it's easier to make vacuum tubes at home...

    The only thing I have left from the tube days is a "Williamson" designed mono amplifier. It weighs in at about 40 lbs and will produce about 20 watts of audio.

    I began with tubes, (as a electronics tech) and still like the concept of the simplicity of the tube amplifier designs. I'm of an age where trying to discern the sound "quality" of tube or solid state would be ridiculous.
    I cannot see where any well audio designed system, tube or solid state, would have any measurable advantage over the other, but I'll leave that discussion to others.

    Are there any tube systems left on the market which you can purchase new?

    How much do they go for? I don't really know much about tubes, except that I liked the sound of a custom built setup my dad had a long time ago.
