You know, I've asked Bob Roberts that same question when I was recapping my GO5. And he told me ... well let me see if I have that email.... yep here it is:
I asked him this:
Also would your Safeback Discharger kit be safe for discharging this
monitor? I read in the B&W Vector FAQ, that it can cause the HV Rectifier
Diode to fail if you don't use Ten 100K-Ohm resistors in series. Is that
necessary? I've discharged raster monitors before(without resistors),
however I don't know if you need to have the recommended resistors in place
for a vector monitor. What do you think? Will your discharge kit work just
as well for this vector monitor?
Bob Roberts responded with this response:
Basic electricity 101 as taught since the days of Edison until now:
"Electricity ALWAYS seeks the easiest path to ground! It does not "care" how
it gets there. If you or your equipment create that path, you will be
placing yourself (and possibly others) in a life threatening situation."
So... if you don't hold onto the ground wire with one hand & touch the metal
frame with the other it will not go through you to get to it's objective nor
will it go through a diode, or any other component, unless you put it in the
path to ground. In the case of discharging a monitor with a Safeback, it's
absurd to think that the electricity with a nice solid path to ground is
going to somehow allow part of it's charge to go in reverse looking for a
much harder path to ground.... yet... the inet stories still grow such as
the one about ketchup containing the HIV virus!
For a common sense view... while the monitor is on there is a constant
17,000 to 22,000 volts applied directly to that HV diode.... not just the
small residual charge left in the CRT.
So there you have it. It makes sense and I've had no problem discharging it with a screwdriver and a wire. Bob knows his sh*t that is for sure.
