It's not a pocket radio but it is DC batteries only, so..
This pic is not of mine, but mine is as nice. the P-780 is arguably one of the best sounding AM battery powered portable radios. It is the best sounding one I have ever hears. It'll really fill the room with sound! The tone control affects bass and treble, rather than just a treble cut control.
It's the first high GE set made with the ideas of maximum performance and durability in mind. It uses 6 D cells and has a quite large speaker so it will play at good volume for a month of days (or nights). The large dial can be lit by pushing a button.
I do take it with me at times. It never fails to please or amaze.
All the details of the set can be seen here. The persons that created this site deserve the credit for the picture.
