Throughout the larger electronics …
WebTubes differ from solid state devices in that they operate using thermionic emission, not weird semiconductor physics. They are called vacuum tubes for a reason, thermionic emission only works in the absence of air. If you are imagining that microwave tubes look similar to the amplifier tubes in your grandfather's radio, you are wrong.
