  1. I thought lee deforest invented it. maybe he just invented the first true amplifier. the electrons keep bounicng around until the current coming out is more than what entered.

    i have a bk butler amp in my car. it is a hybrid which claims to work on the "edision effect" , wherein a blue light is actually emitted in addition to the triodes or diodes glowing orange.

    didja know that some modern planes (soviet ones in particular) use tubes in some vital systems in case of an EMP from a nuke? Apparently they dont get fried like transistors do.
     
  3. everyone knows that. ditto for some medical equipment. russian tubes evolved for military use. the ones in my car are soldered direct to the board-no sockets. no microhonics. no biasing. and, in theory, no replacing since they only run at preamp levels even though they are power tubes. but that 15 second warm up time is the coolest. it kind of fads in with this screechy sound.

    Actually I have a WRX. This is my second tubedriver amp. I had one of the first ones in '97 in my GTI-VR6 Those worked in a more trad hybrid way. even had a contour and would play ss pre-warm up or when the tube isn't giving a signal.

    these newer ones are dead accurate: powerful and no hint of listener fatigue. now check out that single ended for home.

    edit: looks like a hybrid on second glance. mono block. very cool.

    DeForest invented the first triode.
