I'll second Gizmo on the 2SD880.

Try decreasing the value of the resistor, to the next lowest preferred value, and re-measure the current draw.

Circuits like this are usually assymetrical in their waveform. The resultant DC offset applied to the tube causes it to blacken at one end and fail prematurely.
