any more - but it still has its place and
uses. Found a use for a little diode-resistor
logic in a project a few years ago - easier
and simpler than anything else (decoding
multiple switch positions after an interrupt
using minimal pins, a sort of 7->3 converter).
Vacuum tubes are still popular among audiophiles.
A friend just built a small amplifier using a
12AX7 and a couple of EL84s. Then, of course,
there are guitar amps...
tubes IS better - at least AESTHETICALLY. That's
an important bit ... 'technically exact' and
'sounds/looks good to HUMANS' aren't always the
same thing.
China still makes some audio tubes ... as doesPlenty of tubes for sale everywhere, Used to be made in Russia and Czech republic.,
some plant in the Czech Republic (made BY HAND).
Here and there, some people or old shops still
have big boxes of tubes - many still good or
never used. Gotta FIND 'em though - eBay sometimes
advertises a stash.
I've looked into 'neo-valves' ... basically--
cold cathode jobbies where the electrons spew
from a zillion micro-etched 'points' on the
cathode. Beyond that they're kinda ordinary
triodes/pentodes. A merger of old tech and the
means/methods now used to create silicon circuits.
Oh well, nukewar or X-10 solar flare, all that
WILL still work is the tube-based equipment :-)
