- Bemerkung
- The model General Electric L-740 De Luxe Beam-a-Scope has dial lamps: 2 Mazda Nº44. This three-band set covers the broadcast frequencies from 550-1720 Khz and shortwave from 1.7 - 5.2 and 5.2 - 18.1 Mhz. With seven tubes including an RF amplifier, it is a good receiver. Two 6K6 tubes work in a push-pull configuration.
Some info found on Internet by "Chas" (in S. Dartmouth, MA) about the Beam-a-Scope: "The rotatable loops in the later model consoles are usually model specific in design. They utilized different types of input circuitry built within the loop. Often the loop itself was shielded with a wire cage or foil. Sometimes an external antenna coupler is built in. Can be either extra turns on the main coil or a smaller inductor nested within the larger coil. If you want the full performance of the G-E try to find the correct Beam-A-Scope for that radio." We can add to that: Sometimes you will find two loop antennas called "Beam-s-Scopes" by General Electric. Then the second Beam-a-Scope comes into operation if the user chooses the highest shortwave band. With that, a better shortwave reception is achieved without a long wire antenna (which still would be better).
