[Mikremk] demonstrates this with a simple but effective amplifier using a PCL82 triode-pentode. It’s a conventional tube amplifier circuit in which the triode is a preamplifier for the pentode ...
while the other triode-pentode serves as an audio amplifier. The original circuit from which this one is adapted is available online, All in all it’s a neat project, and a reminder that exotic ...
Returning to the now playing screen, Triode features artwork, which is high-res if you’re a subscriber. Tapping on the artwork is a quick way to mute the audio, which is visually communicated by a ...
His grid-triode was no great success as a detector, but it did eventually make modern radio and electronics possible He invented the three-electrode vacuum tube without understanding how it worked.
