Assuming the HV supply is still good, you should have it rebuilt. Neon
signmakers are plentiful, generally do good worrk, and can duplicate any
tube you bring them.

Just a thought.



Even if it weren't, used neon transformers are cheap.

I haven't heard anything but incoherent rantings from that guy though, I
dunno what he's doing on this group. Nothing he posts makes any sense, or
has anything to do with electronics repair.
