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?
Just use a plastic trim pot adjuster. They are meant for monitor adjustment. Monitor boards are fairly safe. Just stay away from the suction cup on the monitor itself and the flyback transformer.
