Oh, not CRT's! If anything they are more dangerous because the demand for shorter (front-to-back) dimensions for a given frontal area requires more "oomph" in the deflection circuitry. The 2nd anode voltage (That's the heavy cable that goes from the flyback transformer to the side of the picture tube) and current has pretty much remained the same over the years, though. 25-30kV and enough current to make you real dead. Heck, even a few minutes after the power is shut off they retain enough charge to knock you off your feet. Ask me how I know ;-) -- Mark Roberts Photography and writing www.robertstech.com
