Bush DAC41

Bush DAC41 radio. Walnut cabinet with a silver mesh speaker grille above a wide black tuning scale and four cream knobs on a pale wood stripUnlike most vintage radios in my collection, the Bush DAC41 doesn’t have it’s own frame aerial. There is, of course, an aerial socket on the rear of the radio.

The set is AC/DC and has long, medium and short wave bands. I must say that, although not one of the most expensive radios of its time, it’s certainly one of my favourites.
