The servo loops use magnetic amplifiers. Mag amps look like transformers, but they are inductors that can be saturated to pass current. I wrote an article on mag amps in the IEEE Spectrum a while ago: https://spectrum.ieee.org/the-vacuum-tubes-forgotten-rival

 @kenshirriff @tubetime I'm always so surprised at how accurate these analogue devices can be. I know I shouldn't be, but as someone who grew up at the beginnings of the calculator era when analogue computing was already underway being replaced by digital counterparts, it always feels like a miracle that these devices don't immediately accumulate so much error so as to become useless a few minutes into a flight. |
Keep watching as CuriousMarc, @tubetime, and I try to get the CADC working, but it will be a long process.
