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 www.nostalgiaair.org/
The "beamascope" is a shielded-loop antenna that eliminates the
nuisance of outside antenna and ground connections. I have now disposed
of this radio.
