I just picked up a RX 507v receiver for $1. The lady said she couldn't get sound out of it. She was right. Does anyone have any idea of what the problem might be? Also, a very basic question...I have never been able to get any receiver to play radio stations. Is there some antenna or something I need in order to do this? I am very inexperienced as you can tell all help will be appreciated. THanks in advance!
