[Boatanchors] Hickok tube tester charts

[Gerry Steffens]

I have a couple of Hickok 6000 & one 6000A tube testers for BA work,
including most of the adaptors.

The question is:  Does anybody know which tube listings are better for BA
work?  I have several dated from the early 60s throough 1971.  I am not
particularly interested in the newer novars and compactrons but rather the
oldies.

Do the newer listings have some of the older tubes removed to make room?  Or
do they just have a few newer tubes listed?

I have these roll charts
	 10-1-62
       Fall 1968
       Spring 1970
	 Fall 1971

 	undated copy of a tube listing book
	condensed reprint of October 1957 roll chart


I do have originals of the Obsolete listings and Foreign listings books for
these testers.
