WebApr 14, 2024 · I have recently bought a Roberts R707 model from 1970. First, I tried it with batteries (Eveready 6V) and it didn’t work, and after that I bought an universal AC/DC adapter (600 mA) which also didn’t work. The adapter had 12V output and couple of converters to fit the radio, but none of them seemed to work. http://www.radiomuseum.co.uk/robertsrepairs.html
