HI! Thanks for the quick reply! I also thought I'd need to find over 30W so that's good news. Do you think something like THAT <https://www.ebay.com/itm/Filter-Power-Supply-Magic-Eye-High-Voltage-DC100-380V-12V-Nixie-Tube-Filament-6V/172730735239?epid=22003184350&hash=item28378dda87:g:lucAAOSwVJhZQULy> is enough for all 18 tubes?
