>"The mag amp can modulate, switch, invert, convert, multivibrate, audio-amplify, radio-amplify, frequency-shift, phase-shift, and multiply. Stages can be cascaded. Simple feedback techniques enable gains in the millions.
The mag amp can even compute. Trouble-proof magnetic binaries replaced the less reliable vacuum tubes used in some early digital computers."
This is my new favorite HN article in the field of electrical engineering...
Basically, what a transistor is to DC -- A Magnetic Amplifier is to AC... plus there is additional functionality...

This device is highly worthy of future study...
