Bush AC2

Bush AC2 radio. Rounded walnut cabinet with a horizontal tuning scale across the top, a gold speaker cloth below it and a knob at each lower cornerThis radio was in a hell of a state when I retrieved it from a friend’s garage. It was damp and the veneer had lifted, the varnish felt like sandpaper to the touch and the radio didn’t work and had some dreadful faults. But it was manufactured in 1947 and I just had to restore it to its former beauty. So far, it’s taken me tens of hours, but the end result will be worth it. Do I want to sell it? No way! The radio is now finished, and it’s beautiful.
