Re: NEC-LIST: Old vacuum tubes

Prof. Baker;

Unfortunately VT4B, VT30, VT31, etc. are only the schematic symbols for
the tubes in a particular circuit - much as a modern schematic might use
Q1, Q2, etc for transistors or IC1, IC2, etc to designate integrated
circuits. Knowing that a transistor is refered to as Q1 or a tube is
refered to as VT30 in a particular circuit is not sufficient to
identitify it's type.

An interesting web site that has links to all sorts of tube faq's and
sources is:
