A good tutorial example for working with 6CW4 Nuvistors is an old
Tektronix Type W plug-in module.  That is a high gain diff amp for
DC to low MHz.  I have one that dates from about 1965 or so.  The
input stage is a pair of 6CW4s that are mounted in a block of
aluminum to apparently equalize temperature.  The assembly is
cleverly shock mounted to help isolate vibration - of which there
is plenty in old 5xx series scopes from the big fan(s), for
instance.  The vertical output is transistorized, so there are some
good lessons there on interfacing -- note the unit is DC coupled
down to 1 mV/cm, though there is a quite necessary DC balance pot
on the front panel.  Finding a Type W manual at a hamfest might
provide some interesting reading for esrtwhile tube hackers.
Actually, a type W itself ought to be cheap and would provide the
nice mounting bracket which could be used for other projects.

It is so much easier to work with solid state components that I
doubt I'd bother starting any new projects with tubes.
