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

is soldered to the
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
Would it be possible to replace the trimmers with Bourns 3362, 3386 or
similar encapsulated types? Bourns also have white and grey types apart
from the usual blue models.

Is this printing on a PCB? Not clear from your photos.
It seems unlikely that ink used on a PCB would be conductive.
