Bruce, Correct, and by adding the series resistor for higher impedance, the voltage regulation at the zener value is raised from 10 volts to some value higher. I actually remember a variable bias control to a tube using a similar circuit, except the fixed resistor was a pot. He shows using this

Paul, No, not the direct light emitted from the LED, but the extra current the cell passed was probably over their limit. I thought of placing the LED's vertical to the Lucite rods, instead of horizontal, or head-on, to decrease the intensity. From the side, a LED, it's much dimmer. The NE-3

John, They used Lucite rods, I shouldn't have said tubes. The neon bulbs are about at the center of the PC board, and the CDS cells are at the edge, so to get the light to them, they used the rods. More than that. They wanted to minimize capacitance coupled between the neons and cells to
