Vacuum Tube Computer P.08.1 – OpAmp Clock: Inverter Upgrades

This episode is so epic, I’ve split it into two parts! In this first part, we take a look at our basic inverter design and see if we can’t improve it some. Then, once we’ve got a design we’re happy with, we do some massive testing on a bunch of different tubes to see how they each perform

Let’s Build a Vacuum Tube Half Adder

In this episode, we build one of the most fundamental computing circuits: a half adder. Being built out of four 6AU6 pentodes running at just 24V makes it even cooler in my book! Thanks for watching!
