I did just recently fire up my judge ITS-1A clock again. It seems like one thyratron has a burning orange looking place inside the back of the tube... I may need to replace that one. I only have spare ITS-1B's... I wonder if mixing and matching them would be problem? Paul aka Judge any idea if that's doable or not?
I wanna build your single tube clock too. I've been trying to figure out exactly what I really need to order from OSHpark and stuff... it's a journey.
