Not the sharpest knife in the drawer on this stuff but agree with Joe that info says that the plate of the 75 should be 160 Volts. The way the schematic reads, unless I'm missing an interconnection dot between the line going from the + on the second electrolytic to the 70K resistors, it appears to me there should be a small negative voltage to ground on the plate, derived from the #44 divider? Seems like the line between the + on the second electrolytic needs to pick up some B+ from somewhere. How about the screen of the output tube? The lines cross, but I see no connection dot.
Call me curious but I don't see how to develop 160V on that plate according to how I read that schematic.
