Wanted tube data

[Fred e holnagel]

Howdy fellow greenies.  I just found the original tube tester Heath TC-1
with original manual.  The original roll data sheet is in good shape.  I
am looking for an update switch setting data sheet for testing tubes
later than 1949.  I would like to keep the tester as it is the oldest
Heath piece I have.  Thanks for any help.  Fred W7PRV
