I recently purchased a Federal Jr. crystal set at a radio meet. There are five binding posts on the top--a group of two and a group of three. Can someone tell me which posts are for headphones--the two?-- and which are for antenna and ground? Thank you.

The very early model was made of brass. Another hint for early models is a label at one of the small sides, showing all the patents, applied to this unit.
