Well there is a good reason why you don't see it cause it ain't there! Is the suppresser grid tied the cathode and then to the chassis?? Like the schematic sez??
I would suspect that the .05 is just scorched form the heat of the bias resistors. Connecting the suppresser grid of the IF amp to the diode in the 75 tube isn't doing much of anything. I'd tie it to the chassis.
