This kit generates high voltages. Always use a suitable enclosure for this kit!
The Kit consists of 2 boards. One for the electronics and one for the Nixie, display tubes
Unpack, inspect and handle the tubes with care!
All components are mounted on a “double side” PC-board.
Components on double sided boards are hard to remove, therefore, DOUBLE check each component before soldering!!!
HINT : The display PCB for the tubes features a tube centre hole, this hole can be used as template to drill the tube holes in
the enclosure
IMPORTANT!
