[RadioSvit]

One of the very interesting English radio - Kolster Brandes KB 530. England 1936. Battery 3-tube radio receiver regenerator with a resonant tunable UHF and a fairly powerful low-frequency amplifier. Two wave bands - "Long waves" and "Medium waves". It is assembled on tube manufactured by the English Companies Mullard and Cossor old types with 4, 5 and 7-pin tube caps. Judging by the quality and perfection of the design and high-quality finishing with expensive varieties of veneer, the receiver was created for the well-to-do part of radio listeners in remote areas of the British Empire where electricity was still missing.
It is powered by a 120 volt anode battery and a 2 volt radio tube battery.
The receiver used several interesting technical solutions that are rarely found in other structures, for example, a range selector by pressing and turning the tuning knob and the indication of the included range in a separate window.
