The Loewe 3NF was an early attempt to combine several functions in one electronics device.
Produced by the German LOEWE company as far back as 1926, the device consisted of 3 triode valves (tubes) in a single glass envelope together with all the fixed capacitors and resistors required to make a complete radio receiver. The resistors and capacitors had to be sealed in their own glass tubes to prevent them from contaminating the vacuum.
The only other parts required to build a Radio receiver were the HT and LT (A and B) batteries; the tuning coil; the tuning capacitor and the loudspeaker. The device was produced not to enter the Integrated circuit era several decades early, but to evade German taxes levied on a per valveholder basis. As the Loewe set had only one valveholder, it was able to substantially undercut the competition.
One major disadvantage of the 3NF was that if one filament failed, the whole device was rendered useless. Loewe countered this by offering a filament repair service.
Loewe were to also offer the 2NF (two tetrodes plus passive components) and the WG38 (two pentodes, a triode and the passive components).
