Cool.
As we all know the main advantage to this clock using tubes is (of course) that it sounds better, due to the use of the tubes!
I happen to have a pile of those Beckman modules, mine have octal plug ins, and they are still in the Beckman counters that I picked up for the rows and rows of dual triodes (which are industrial versions of 12A_7 tubes) and the associated parts... maybe I need a nixie clock??
