This Motorola c4p vintage AM tube radio I believe completely works and has been tested. The only thing I have never been able to figure out is how the alarm works. The rear setting dial will set the alarm and the clock, but I never understood which hand is for the alarm. Otherwise, the radio works, the backlight works, and it has all the turn dials that also work. If you have any questions, don't hesitate to send me a message. I will make sure and very package and ship the radio. Thank you
