[Hallicrafters] Definition of a tube?

[Glen Zook]

You missed the "key" point in the definition:  Field
Effect!

A tube (or "valve" as our British cousins call them)
is a form of field effect transistor.  Thus, they are
capable of bringing the field with them no matter
where they are used.  If they could only be used
outside then they would be called field transistors
and not field effect transistors.

Now horses have worked in the fields for millenium
before tractors.  It has just been in the past about
150 years that tractors have worked in the fields
(remember that there were steam tractors in use before
the Civil War, not many, but some).

If a tube is a field-effect device, then pray tell how
the heck do you explain that they work pretty well
aWAY from fields, *inside* the house? How can being in
a field make something work? Besides tractors, I mean?
