Yesterday and today I worked on a wooden base plate, to put everything on including the heavy transformers. I glued three pieces of wood together, cut it and painted it. The aluminium base plate will sit on the wood using a hinge mechanism, so that it is easy to inspect the back where all the soldering should take place.

I soldered the rectifier circuit with EY88's. so I now have something like 200V and 400V. The EY's and all other tubes that a filament voltage of 6.3V will be connected in chains of 4, connected to 25.2V. Or something in that neighbourhood. 

I preliminaruly connected the nixie tubes so that display something (it's currently 12:06 all day). I started wiring the first dekatron circuit. It gives a sign of life but it isn't spinning yet.
