The ground lead from the tube is attached to the neckboard.

I hope not :-(. Isn't it possible that the neon is being lit up because too
many volts are going to the neck board? Maybe I have a runaway voltage or
something...

Maybe my description was bad...the spark/arcing is happening in the neck of the
tube; looks like some heater parts are sparking together (reminds me off a
spark plug).

I'm not having good luck with tubes lately...I do have a spare Amplifone tube
laying around though...could I use that if I had to? I assume I'd have to
replace the neck socket.
