(1966-1968) FM/MW/LW/SW Portable radio, 1x1W
This model replaced the Beolit De Luxe 611-FMT. Outwardly it was very similar, but can be easily recognised by its restyled tuning dial, white (instead of black) pushbuttons and slightly different control knobs. The new knobs were all the same size (previously the tuning knob had been larger) so to make the tuning control easier to recognise at a glance it was given a black centre.

Internally the receiver circuit remained largely unaltered but the audio amplifier had been redesigned. The amplifier in the original version had used five transistors and although capable of reasonable performance had in truth a little too much gain, leading to excessive background noise and a volume control that could prove difficult to adjust. The new circuit had only four transistors, replacing two PNP germanium types in the preamplifier with a single low noise NPN silicon device. This change brought improved performance at the cost of slightly increased battery consumption. Text copyright © Beocentral. Unauthorised reproduction prohibited.
