Nicely built, but the wrong schematic was shown because the upper PCB uses HV5122 parts, and the schematic showed K155D.
My only concern about using socket pins in this case is that they were already soldered to the board, so plugging-in the expensive IN-18's may subject them to stress. I individually numbered mine, slid the socket pins onto the tube, THEN soldered in-place; the socket pins are custom fitted to each tube and there's almost no stress on the tube. I also 3D printed pin collars, though they are mostly cosmetic. That IN-18 with the 9110 date code must have been one of the last few built.... No heat-sink on the MOSFET, and could probably use a few more mounting holes [Did you notice the display burped when the PCB was wiggled ?] -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
