RE: Why?

You have a pair of ECC83 drawing current through a series connection of 1K and 22K resistors. Figure each half does 0.001 amps. So you have 0.002 amps going through a 22K resistor. The grids are referenced to that point through 2M2 resistors. 2 millamps across 22K should develop 44 volts. So I would expect the grids to be 44 volts above ground. The cathode has an addtional 1K resistor would would make the cathode 2 volts above the grids...as in 46 volts above ground.

Or maybe I see it all wrong?
