AM Chrysler Solid State Radio

Does it do anything at all? Usually the electrolytic caps dry out and you need new ones.
Nothing, no static or anything. The switch makes a solid "click" sound when turning the knob on and off. I need to get under the dash and give it a look see and if I'm lucky it'll just be a loose wire. What are the "electrolytic caps" you spoke about? Thanks!
