I'd rather not be the electron sink In this case.
I've never taken a
hit off of a CRT have you?
Yes, from a 26" CRT in a colour TV. It threw me across the room and
taught me a lesson I'll not forget.
BTW, if anyone has CRTs lying out of circuit, don't assume they're safe
either. The EHT in normal use forces electrons into the glass, and when
disconnected they very slowly migrate back to the aquadag, producing a
substantial voltage. I remember seeing this demonstrated on an
electronics course several decades ago. Which is where I /should/ have
learned about discharging CRTs *through a suitable resistor* :-)
