[Heathkit] Need Eico 666 Test data for 572B's

[Ken Kaplan]

The 666 manual otherwise has docs on how to derive settings for a 
non-listed tube but I don't think the 666 will provide the 4 amps the 
572B needs for its filament. I have an Eico 667 it groans with a 6146 
which only wants 1.25 amps.

I've checked (googled) all online sources and my 666-07 data chart and supplements for both the 811 and 572B tubes and can not find anything.  Has anyone developed a set of settings for the Eico 666 tester which would enable me to determine the relative emission and/or shorts/leakage for either oif these tubes?  Much appreciated.
