    A computer powered by a vacuum tube is not quite as powerful as your average pocket calculator.

    And about as efficient as Windows Vista.

    Vacuum Tubes aka Radio Valves do have some advantages in limited areas
    1/ EMP Resistant = Yes
    2/ Can operate into the GHZ range and higher = Yes
    3/ Give a purer Sound = NO
    Total FAIL. the Audio response and purity spectrum of Audio valves is purely subjective and argumentative.

    Nice to see a post from someone who knows what heis writing about! Thanks.
    P.S. No judgements or politics either. Thanks again.

    I originally learned electronics during the vacuum tube days, then had to re-learn electronics when solid state devices took over. I have fond memories of building my own radios, transmitters and receivers using vacuum tubes. Nothing like a good 350 VDC B+ supply to teach you respect .. ha ha!

    Hey, Cooncat, me too. After the B supply for a pair of PP 6L6s knocks you through a wall, and leaves your fingers bloody and smoking, you have learned more about electronics in one second than in months of classroom training.

    Try fixing your first TV at age 6 or 7 simply by replacing burnt out vacuum tubes.

    Many drug stores had vacuum tube testors and replacement vacuum tubes. Any tube that wasn’t glowing was taken to the drug store and self-tested. You bought the most common tubes right there in the store. Radio Shack had them too.

    I believe they called it “Fluoroscope.” Incidentally, I read, many years ago, we had gotten hold of a Soviet MIG and tore it apart to analyze it. We laughed, at first, when we discovered they were still using tubes when all ours had transistors, etc., until we also discovered that tubes were less resistant to jamming and radiation.

    Is that pole dancing caterpillar race seductive to a social butterfly?

    Actually the speed statement is a bit misleading at best. Yes, they can make oscillators that operate at high speed (think radio), but they do NOT “switch” at high speed (think computers). That’s one of the reasons we switched from tubes to transistors because they DO switch at higher speeds (and use LOTS more power).
