IMPORTANT SAFETY NOTICE

Some radios have two pins on the rear for the mains plug, such as the Bush DAC90 and DAC90A. I will disconnect and insulate the two pins and fit a new mains lead directly to the radio, unless specifically asked not to by the customer. I will leave the two pins in place so as not to devalue the radio.
