    Was looking a DIY headphone amps http://www.pmillett.com/nuhybrid.html and saw this http://korgnutube.com/en/

    New to me, maybe not to you, but I thought it was pretty cool.

    That is an interesting "tube".  I guess tube rolling would be rather difficult LOL. Operates at extremely low voltages - 0.7v heater voltage, B+ 5 to 80V.  Must last a while as the picture above has it directly soldered to the circuit board.  

    The 2nd link above did not work for me but this one did.  Datasheet further down.

    Sorry for the bad link.
    Maybe you could solder in a socket for that "tube" (are there others to roll in?)
    like the ones that used to hold your computer memory.
    Haha. Old guys who remember that stuff...

    Ohhhh! 256K!!!!
