How do I draw a stereo amplifier based on vacuum tubes? I can't find vacuum tube symbols in the library. |

Vacuum tubes are essentially thermionic devices where a heated cathode emits electrons into a vacuum, and these electrons are controlled by other elements like the grid and anode. The vacuum allows electrons to flow without collisions, so the tube can amplify signals — small changes in grid voltage lead to large changes in plate current. In modern circuits they’re largely replaced by transistors, but tubes are still used in high-power RF and audio applications because of their characteristic distortion and robustness in certain designs. @ Wacky Flip |
