The Bush DAC10 radio was introduced in 1950. It uses a chassis very similar to the DAC90A, but the DAC10 has push button pre-set station tuning as well as manual tuning. There are two pre-set buttons for medium wave and one for long wave. I specialise in repairs, servicing and restoration of Bush DAC10 valve radios so, if you own one of these lovely radios, don't hesitate to contact me.
