    Previously, a failed tube always meant a treacherous operation to delicately remove the tube whilst trying to preserve all traces intact. Whilst this was certainly possible, It was never easy, and made it uncomfortable to give a Nixe Clock as a gift in case a tube ever failed. With the QTC system (‘Quick Tube Change’), each tube is soldered only to its own mini ‘tube cell’ PCB. A tube can be changed in minutes with no danger to the main PCB. The small addition in cost is dwarfed by the huge advantage this gives. A single main board is capable of driving tens of different types of solder-in Nixie Tube. You can even completely change the tube type of your clock by installing new tube cells and tubes.

 Drive Mode

The former K155ID1 / 74141 nixie driver IC is now replaced by a modern HV5812 High Voltage Driver IC by Supertex. With 20 outputs, it is able to drive the six Nixie Tubes in a very comfortable 3X2 multiplex.

GPS Time Synchronisation
Included is a GPS Time Synchronisation Receiver, which automatically receives time and date from GPS satellites. Please note, the GPS needs to be within 2m / 6ft of a window.

12V Power Adapter
A high quality power adapter for your country is included, with a long 1.8m / 6ft cable.
