This is more for the video arcade guys I suppose but can apply to Pin2000. Is there a difference between a regular screw driver with an insulated shaft and what I have heard called a High Voltage screw driver?
Was thinking off adjusting the brightness pot on the tube but have been told to use a HV driver. Or is it just a matter of being extra careful and you'll be fine?
Be careful adjusting the "Screen" Brightness... You don't want it to be too bright, as you are only driving the screen too hard, leading to premature failure. Generally, adjust the screen brightness so the background of the picture is black, and no raster (diagonal lines) showing.
Using plastic tools for adjusting the monitor chassis is best, but generally I don't bother. I've had more than my fair share of zapps over the years, so I suppose I know what I'm in for
