Testing 6146B/8298A with a 177/b

I have been fighting with a SB-401 heathkit transmitter, and I have come to
the conclusion that the finals (6146B/8298A) are probably defunct.  I
tested them with a simple emission tester and, although barely, they pass
as "good".  I 'd like to use my transonductance tester, however, for a more
reliable test.  Problem is I don't have the settings for these tubes.  Nor
does the extremely detailed collection of test setting prepared by Nolan
Lee (http://www.acadiacom.net/nlee/i177_index.html).
Anybody can help?
