Simpson Meter Clock
I've not come across one of these little Simpson Meters before, lovely proportions and I've just managed to squeeze a Nixie Clock inside, that uses the little CD43 Nixie tubes. I would date the original instrument to the late 1950's. There's even a little label on the back saying the battery was changed in April 1962, which has been scribbled out and replace with November 1970!
A beautifully made piece of equipment, you can tell it was a very high quality item when new. Made entirely out of Bakelite and glass, with a stitched leather handle. Converted into a clock to the highest standards, I particularly like the writing on the dial that says 'Vacuum Tube Voltmeter' quite fitting to have Nixies in there.
- 4 off Japanese Rodan CD43 Nixie tubes
- Hours and minutes display
- 12 / 24hr modes
- Leading Zero suppression
- Slots / Cathode poisoning prevention routine
- Tube life in excess of 15 years
- Totally unique item
This is a one off piece, I only have the one of these and I've never seen another meter like this. Measuring 14cm wide, 18cm tall and 8cm deep, it's the perfect size to fit anywhere. Once it's gone it's gone!
