I have several power strips with flickering pilot lamps in the rocker switches and a couple that are completely dead. I've always assumed that the cathodes in NE-2s aren't the greatest. > I hope the new clock will turn out to be more reliable... I'd love to know how these Soviet era neon indicator lamps (including the thyratrons) hold up over time and how well the thyratrons would work using a low-voltage trigger. Can they safely be driven from a 5V chip or would opto-couplers be necessary? Terry Bowman, KA4HJH "The Mac Doctor" Q: Should car stereo speakers be pointed to the rear for more thrust or up for more traction? A. On long trips, the 20- to 30% improvement in gas mileage you might get with speakers pointing to the rear is certainly worthwhile. On the other hand, if you drive on snow or ice, the extra traction of speakers pointing upward gives you added control.
