Can you light burnt out 40 W tubes
Actually i found this as a challenge in this site
"Challenge: Make a DC tube circuit using diodes an condensers for lighting burnt out 40 W tube lights
We make a DC tube circuit, where using only diodes and condensers we get a pulse of 600 V DC and this is used for lighting 40 W tube lights that have a burnt out filament. We have put back in use many such tubes (over 200 till now). We give this as an exercise to students. However we find some burnt out tubes don't work and some do. We do not know how to select the tubes from the junk tubes.
