There are only a very few wire pigtail Ne's made. I think there was a means of
ID'ing which is in there by looking very carefully at the glass pinch area.
There is something stamped into the glass as I remember. You might ask someone
like BulbDirect that specializes in lamps.
I remember NE2-D and NE2-J as well as the NE2; different wattages,
IIRC.

That was my first impulse; however, the manual (paragraph 5-27) states
that "physical alignment and selection of the neon bulbs are critical"
and that replacement of the entire assy is the only thing to do.
Can you speak to this at all? If I _do_ replace the neons, are
standard NE-2 bulbs the right thing to use?
Thanks for your help!
