4 Tube Avo Clock Module MK III
A Fully Assembled and tested 4 tube IN-12 Nixie clock module designed to fit inside Avo-8 MK III and earlier range of test meters
The Module is designed as a replacement for the original Avo meter movement. It is also completely reversable, should you wish to turn your clock back into a meter!
Now in the MKIII design, incorporating a light level sensor so it will automatically dim the tubes at night.
The process is fairy simple - Remove the cover off the Avo, unscrew the battery box from the casing and then there are 2 screws that hold the dial movement to the front panel. Unsolder the 2 wires that connect the movement to the front panel. Carefully remove the original movement and keep safe if you plan to reuse. The Nixie module then just screws in where the original movement used to fit.
You will need to make some small holes in the rear of the case for the power connector and 2 switches and then reassemble
