Allied- Space Spanner Regen 3 tube mains TRF, tube lineup 50D5, 35W4 and 12AT7. Covers broadcast and the shortwave band from 6-18 Mhz. All of the radio receiving and detecting and a stage of audio amplification are done by a third tube, the 12AT7, a real tribute to the simple and efficient design of a regenerative receiver. A later version sports a two-tone color on the front panel. |

Together with the likes of the Star Roamer and the Span Master these are
the most classic and collectable kitset regens available today and are
sure to have kicked off the careers of many a boy builder.. They are extremely simple, low power, pure fun & frustration to operate, immune to imaging and signal overloading and able to resolve SSB without a product detector or BFO. They are very sensitive if operated just on the verge of the detector breaking into unwanted oscillation. Be sure too try one out sometime. |
