The triode is one of the simplest kinds of vacuum tubes. Inside its evacuated glass envelope, the triode really is just a few bits of wire and metal. Triodes are able to amplify signals simply by h… ...

This addition shifts the triode characteristic curves 100V to the left (Figure 5 ). Note the load line and that the plate can now draw 150 mA at a plate voltage of only 100V, rather than 200V as with ...

The Unison Research Triode 25 Integrated Amplifier currently under review sounds absolutely stellar and I’m rather smitten. One of the tubes already put on a strange glow and the crackle through my Q ...

I tested a pair of Écoute Headphones to figure out what's going on with them and have a sample for you. 0:00 intro 5:06 Audio ...

[Tomtektest] had a dual triode that has lost its vacuum integrity — gone to air, as he calls it — and decided to open it up to better expose its inner workings. (Video, embedded below.) ...

The Triode 25 can be switched from Pentode to Triode mode at the flick of a switch, even while you’re listening to music. Pentode and Triode refers to the configuration the output valves work in – and ...

He invented the three-electrode vacuum tube without understanding how it worked. His grid-triode was no great success as a detector, but it did eventually make modern radio and electronics possible ...
