So ive given up on my old power transformer and im ordering parts to build a new one. While im at it I want to get some PNP transistors because I plan on multiplexing my nixie tubes. I really don't understand these things a whole lot yet, how do I pick one that can switch 200ish volts and not fry my…

How to pick PNP transistor for nixies

We always used MPSA42 for NPNs and MPSA92 for PNPs for HV circuits like this. Cheap and In Stock at Digi-Key (among others) .
