That looks top mate
Looks very smart.
You have an eagle eye... its a PIC16F1936, whatever the heck that is!
All the board and components are new... its just the tubes that are old.
It's a pretty standard 16-bit microcontroller, I used an earlier version (16F877A) in quite a few projects at uni and at home so I'm quite familiar with the family.
Nowadays no one makes their own micro boards, they just use an Arduino...
Reason I comment on the newness of the K155 driver is that they aren't made any more! The drivers I used on my clock were 80s-vintage, and IIRC production must've stopped in the mid-nineties unless someone's restarted. OC all the other bits apart from the tubes will be brand new.
