Alright so here's the chart I mapped out with one of my JAN 2C26A tubess, the equipment I have at my disposal and the Open Office equivalent of Excel (which crashed repeatedly while trying to make the graph) for anyone that wants to have a go at using these in their own amps.
I would have made them all nice straight lines to smooth out the results of my rather crude testing set up of swapping out resistors and applying 1.5 to 12v to the grid but I couldn't figure out how, still it's more than is in the datasheets you can find online and it allowed me to put together a working amp.
