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 ...

Despite the oldest solid state audio circuitry now qualifying for a pension and a bus pass where this is being written, the thermionic tube retains a foothold in the world of audio — cherishe… ...

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 ...

[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.) ...

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 ...

Stamped: "893-A / Sylvania." Donor’s card reads: “Power triode made by the Sylvania Corporation for use as a modulator, amplifier, or oscillator in radio transmitters. Filament is pure tungsten in ...
