10 thoughts on “More of Igor’s Thermionic Valves

  1. The only tubes I use in my Fender Blues Junior. Spendy yes, but you get to listen to that warm tube tone (and smell) the rest of the night! Thanks Igor…

    • 6CG7, 12AU7, 3A3, 12DQ7 being the most popular in my hoard. And, yes, I still have my 1934 Signal Corps tube tester(s).
      I even have some catseye tuner tubes!

      The reason for the “warm tone” is that most of the “mainline” amplification tubes had a high-frequency rolloff. You will find that high-end amplifiers of the day had specific amp sections for the high freq’s.

      Oh, and I also have an old vacuum tube Radio Control transmitter AND receiver from the 1930’s – still works, but I literally have to build the B battery from 9V battery stacks to make the transmitter work. The receiver has a one tube “acorn” style tube, even rarer.

  2. Hearken to the days of a tube tester provided gratis by the corner drugstore. So happened they held a rich depository of fresh tubes so none should languish in want. Except we had to combine our coins to afford the more expensive.

    Its how man stepped onto the moon, you know.

  3. Obligatory “me, too.” Got a box full of tubes, a couple of tube-era radios, shortwave and ham transceiver. Tube tester under the bench. Memories of going to the drugstore to test tubes for the folks.

    • Got a tube tester, two Hallicrafter Ham transmitters, and two Hallicrafter receivers (one Ham & one general coverage).

      I remember the tube testers at both the drugstore and the grocery store where I grew up.

      Real radios glow in the dark!

  4. I have one. Mounted on a little wooden base. Gift from my former electronics supplier at my last J O B I keep it for sentimental reasons from my utes. We always had the TV repairman come to the house I never knew what he did till I got old.

  5. Pic’y looks like Rusky Mil 6922’s (though of course I could be wrong!). GREAT tube, in my tube phono stage (no line stage … pair/dual mono Shallcross passive ladder attenuators). Feeding a stereo 300B amp (of course).

    Signed, One-Way, vintage 12″ Alnico, on open baffle. With NO crossover. Yummy.
