Default Roll Chart for 6DJ8/6922/7308 on Philco 9100 help

Hi all,
I just bought a Philco 9100 (Hickok 533A alike) intend to check my 6DJ8/6922/7308 collection. But this model was pre-6DJ8, its roll chart doesn't have these tubes listed.
I use the numbers from 533A but the Gm reading are way off
I went back and compare the roll chart on several tube types listed on both models 533A and 9100 and notice that the matching are Filament/Selectors/Press button.
Others(which are important) like Bias/R-G/Gm # are different

So if any guru here have (or come up with an equivalent dialed parms) for Philco 9100 to test 6DJ8 family - I would very appreciate your help

Thanks In Advance
