Thyratron

RW I remember the 6SN7...

RW Are the numbers up that high by now? The latest I remember is a 6AL5.
RW Are they still made?

Industrial numbers were into thousands range. Many tube types are
still being mfg'd overseas, China, Russia, etc and apparently there is
substantial NOS of some types around. Guitar amplifiers are a constant
market since dsp technology failed to replace their sound.
