Jürgen sent me this work-in-progress photo a few days ago. But, I'm bad about posting things quickly
"For a full length bargraph now the circuity draws only around 300mA @5V --> 1.5VA and this creates 10mA @ 120V --> 1.2VA (only 0.3VA losses); but I must also connect the MC34063A to the voltage doubler circuity (the flying IC "ICL7660" with the two diodes and the two capacitors) and not only the new BC639/640 driver stage for the MosFet...as the converter will shut down when the supply voltage is lower than exact 5V and it should normally just work at 4V."

I now see where I got wrong with all my kits. you see, I was under the belief that the components were supposed to be soldered to the circuit board.

These are really cool tubes. Does anyone know what the intended application was for these tubes?
Let there be neon light!
