Hi Chris,
Quote:
Will you be including Nixie type display tubes in your publication? Also did you receive the emailed pics of the Blackstar Meteor
Afternoon Dave!

Meteor Pics received with my grateful thanks!

I would like to feature the AVO DA112 Nixie DMM but "Nixiephoolery" prices are well to the fore – last one I saw on sale was four figures and that was a dead one, and I've not come across the circuit yet!

However, there's no reason why I can't use a diode–matrix operating high–voltage switching transistors on a DVM chip or something like the Siliconix LD120/LD130 and feature it as a "retro" DMM project!
