I tried another exercise with those pesky zeners. The exercise had some things that give me grief, So i thought it would be a good test.
Here is the link to the exercise and the schematic.

I wired it up as shown using exactly the specified components other than the lamp and it's socket.
I expected to get a light then I was gonna put in the metering points. Alas no light. I checked lots of times and was unable to discover any error.
So. I substituted 16v instead of 9v and it lit up though the resistor did not last long. No surprise there.
So, could the makeup of the lamp be causing my grief ? In that it is quite different than what was specified.
