So I've decided to make nice big beefy 1950's replica of Nixie clock inspired by old HP gear. I will use XO for start and later 10Mhz OCXO.
First designing relays for that authentic clicking sound of old gear, 45 relays all together 1 relay for each digit. relays connecting tube cathodes to the ground.
First testing of tubes, in my project I'm using IN-1 Soviet tubes and DC step up 180V
