"There is something more powerful than each of us, a combination of our efforts, a Great Chain of industry that unites us. But it is only when we struggle in our own interest that the chain pulls society in the right direction..." - Andrew Ryan

These electron tubes were crucial to the functioning of the computing banks of The Thinker, ranging from enforcing direction of current flow to amplifying it. However the fragile glass construction meant that they had to be frequently replaced in face of the skirmishes from the Rapture Civil War, or simple Splicer violence.
Behind the ScenesEdit
- The name "Karla" is inspired by the name of a BioShock 2 and Minerva's Den developer, Karla Zimonja. She is also referenced in BioShock 2 as a possible name for a Security Bot.
- Like the numerous punchcard machines, vacuum tubes fit with the period of computing technology available to Rapture. Today, they have been largely supplanted by the relatively lightweight transistor and further Integrated Circuits.
