Kungs LL. Sweden 1932
A very interesting device of the transition period, when the design of a European radio was transformed from a utilitarian instrument with a loudspeaker in a separate package to a one-block familiar to everyone in a beautiful furniture design. And naturally, the cases of such radios were very often made at furniture enterprises, which is why they had the appearance of expensive furniture.
From a technical point of view, there are also many original solutions. The receiver is designed for operation with electric networks of exclusively direct current (!). Therefore, the kenotron is absent in it, and the filaments of the radio tubes are connected in series with each other and the ballast resistor. Naturally applied radio tubes with high filament voltage. Aluminum chassis - the design is very solid and good quality. This is a regenerator with non-resonant UHF. Two triode REN 1821, the first in UHF, the second in the detector. At the exit of RENS 1823d or PP2018 from Tungsram.
By controls. The right knob is the regeneration threshold, the central knob is the tuning, the lower left is the switch MW, LW, the left upper is the connection with the antenna, that is, the sensitivity.
