The entire document as a single PDF file (1.7MB) has been available for
some time on my website at

<http://deane.bio.ucalgary.ca/HeathTubeData.pdf>

Note that this is useful also for the older Heath tube checkers such
as the TC-1, TC-2,TC-3 (not the TT-1 tube tester) if one changes the N
in the setup to whatever the highest letter is on your tester (the
position corresponding to the plate/grid cap)
