About 35 volts on the plate, -0.5v on the grid. That's taken with no signal input, to compare to the voltages on the schematic. With signal input the voltage goes up to about 65v on the plate, -4.0v on the grid.

My dropping resistor in the power supply that I experimented with will drop the voltage to around 40v on the plate with a signal, 30v without. It doesn't have much effect on the grid voltage.

The additional capacitor I added barely effects the grid voltage as seen on the vtvm, but the effects were visible on the scope, as I posted above.

For V102B: about 36v on the plate whether there is a signal applied or not. 0v on the grid with no signal, about -0.8 with.
