Someone else might be able to confirm this but it looks to me like you connected it up the correct way.
I just wonder one thing, if you see the light flickering as you say, can you actually measure (with a scope) that the voltage across the tube changes? If the voltage doesn't change, the tube is still doing it's normal zener function. Michel On Sep 30, 8:20 am, Paul S <[email protected]> wrote: > Hi!
