GE Portable Radio Model LB-673 

Valve Radio LB-673 This American portable mains / battery radio is intended to work with a LT supply of 9 volts an HT supply of 90 volts or an AC/DC supply of 105-125 volts at 40-60 Hz. It is a single waveband superhet with one RF stage and one IF stage covering the range 540- 1700 Khz. The valve line up is as follows: 1N5GT, 1A7GT, 1N5GT, 1H5GT, 3Q5GT and 35Z5GT. Service notes and schematic diagram from The "beamascope" is a shielded-loop antenna that eliminates the nuisance of outside antenna and ground connections. I have now disposed of this radio.
