Do you get a sound when you rub your finger on the needle? Maybe the phono/radio pushbutton switch isn't making contact?
Or maybe check the 7A7 phono amp tube? I think if you touch the tip of a soldering iron to the grid pin of that tube, you should hear a 60 cycle hum. With the iron off but plugged in.
