Valve-o-Tron

This is the 'Valve-o-Tron' Very impressive looking clock, based on an old Wheatstone Measuring Bridge. Uses four of the Red varnish coated GN-4 Nixie tubes and has an A101 Dekatron in the Centre.

The Valves on top all glow subtly, as near as I could get to using the original heater filaments. Within the clock settings you can vary the lighting level from 0-9. All the components fitted to the top are vintage, and came from a very old Valve based oscilloscope that weighed best part of 35Kg!
