I recently bought a prettier one of these than the one which is in this post from a couple of years ago.
I suspected at the time I got the original that it was probably damaged, and the condition of the newly acquired one would seem to suggest that is the case.
Here is the original tube CX1622:
and here is the "new" one CX1140LD:
The original one has fly leads, but is basically the same tube.
Here is a short spec sheet on the tube:
The spec sheet shows it runs at 33kv @ 1.25A. Not static electricity. It is rated to handle 1000a spikes.
