Supply Voltage B+ 11.8 v
  B+ voltage - Plate Voltage = Voltage drop across Rp voltage drop across Rp
Resistor Value Rp 46 k Drop= 3.2
Grid R-Value for next stage Rg 1000 k
 
Plate Voltage Vp 8.6 v (Rp*Rg) / (Rp+Rg) = Adjusted plate load resistance
  43.97706[1]
Internal Plate Resistance Ra 12.5 k
 
Grid Voltage Vg -0.7 v Voltage drop / Plate resistor value = Current across plate resistor
  Current= 0.0696 Plate current
 
 
Internal Grid to Cathode Rgk 0.5 k
