  1 Hello Friends

That is "Evening glow-hobby".Who made example EABC80 today? What happen tube manufactures and where they went at time when transistors came? Where are today tube´s bilding machine. I afraid that they were broke. Is it possible that keep list or section for Radiotubes Manufactures like Radio Manufactures from every place world. That list can be shows activy factorys and of course closed factory!

  2 Dear Eero,
I believe that many of the tube building machines ended up in Russia and China, where most of the tubes come from now. At least, all were not destroyed.
