Re: Piece display PCB
Examine the board for bridges and errors. Once you're sure it has been assembled correctly solder two thin wires here:
Take one of the printed coil PCBs and solder it to the two wires using the smallest neatest possible joint.
Plug a suitable nixie tube for the board into the two pins, the anode can be identified by the white ceramic coating on the inside of the tube. This connects to the 'HV' pin.
Now repeat for the other 31 pieces
