Anyone know or have amazing abilities to discern ancient handwriting? I can't make out either the B+ or the current draw, and I'm trying to do some load-line calculations.
ELA M 251 (non export) B+?

B+ 120V, plate current 0.5ma, for either AC701, or 6072 versions.

The interesting thing about that schematic is the 8M grid resistor instead of the 30M used in the 6072 version. the 30M works well with the Ck12 and reduces the huge low end to a more controlled sound for close up vocals but I would expect 8M would sound like a telephone in that circuit! unless the AC701K somehow compensates for this??
I don't think changing the grid resistor would do much to the low end. It could however load down the capsule and potentially affect the top-end and/or sensitivity.
