Discharging CRT anode and capacitors on a VT52 DECscope

John> You may or may not hear a snap, or see a small blue flash when John> you get the tip of the screwdriver close enough to the anode John> connection - it depends on how well the CRT in the terminal is John> retaining it's charge. One small point: In this process, be sure you keep your fingertips WELL away from the metal shaft of the screwdriver. The most natural position for the fingers is close to the metal, occasionally slipping right onto it. That's NOT where you want to be when you're poking around high voltages. There are special "safety" screwdrivers (designed/approved for work in live mains power systems). Those have shafts that are insulated right up to the tip. You could give yourself a little extra safety by wrapping a few layers of electrician's tape around the top 2-3 inches of the screwdriver shaft. But keeping your fingers on the top half of the handle is the thing to aim for. paul
