Hi Greg,
No, not ESD... My friend touched the shell on the cable to an external time
source (clock ground) and the label (-270VDC). Not sure exactly what he was
doing at the time to touch both, but there you are.

If this uses an isolated supply (such as from a wall-wart), you need to
touch 2 circuit nodes at different voltages in order to get shocked.
Any chance this was from electrostatic discharge (ESD) ?

There is a small tab at an interior edge of the label plate sticking out
toward the tube carrier pcb in the middle where the tube carrier connector

Hi Terry,
I guess I could have been more clear... The label plate ink is only
*moderately* conductive; black ink on a somewhat flexible white
substrate... the label is not FR4 pcb material and there are no metal
layers. I have no experience using this material and am just letting you
know
