Triode or "Audion" tube |
1906 |
In 1907 De Forest patented a bulb with the same contents as the Fleming diode, except for an added electrode. This "grid" was a bent wire between the plate and filament. De Forest discovered that if he applied the signal from the wireless-telegraph antenna to the grid instead of the filament, he could obtain a much more sensitive detector of the signal. |

DT800 |
1922 |
Among the scarcest items ever to ship out of de Forest's Jersey City factory. Designed to pair up with Deforest's DT-700 radiohome receiver, this two-stage amplifier comes in a walnut cabinet identical in size and shape to that of the DT-700, with audio inputs positioned to correspond with the audio outputs of the radiohome. The connection diagram on the inside of the lid details how the two components are to be connected to each other and to the battery supplies. |

Radiocraft Radiophone |
1922 |
Radiocraft was purchased by DeForest in 1922 as a means to acquire rights to the Armstrong regeneration patent. Unfortunately, Westinghouse apparently didn't approve transfer of the patent license and the Radiocraft models were discontinued after a short time. Today they are very hard to find. This set was produced by DeForest under the Radiocraft name shortly after the Radiocraft acquisition. |

Contains a crystal detector and 4 tubes, rather than being a 5 tube set. Not many of these were sold. The 4 tube model was redesigned into a 5 tube set and the crystal detector eliminated. Then the 4-tubers were recalled and traded straight across for one of the 5 tube sets, which makes those D-12s that still have the detector an especially rare set, much more so than the 5 tube model. The circuit for this set is almost identical to the D-10, which it is sometimes confused with because of that. |
