Looks very smart.
You have an eagle eye... its a PIC16F1936, whatever the heck that is! ![scared :scared:](https://www.mk5golfgti.co.uk/forum/Smileys/newsmileys/scared.gif)
All the board and components are new... its just the tubes that are old. ![happy2 :happy2:](https://www.mk5golfgti.co.uk/forum/Smileys/newsmileys/happy2.gif)
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.
