Agreed.... ditch the choke... you don't need any additional decoupling. One last model shows the following assuming a 350 volt supply and a 6K load.
Useing a 1.21K cathode resistor, it works best to minimize distortion and balances the transfer characteristics. Idle current is a bit over 44ma, plate voltage is 294 and grid bias (via the cathode resistor) is about 54 volts. Output power calculates to 3-watts with 3.7% 2nd harmonic distortion and 3rd harmonic very low... around 0.02%.
