Jukebox (Fallout 3)

The Jukebox is a House improvement you can buy for your Megaton House or Tenpenny Tower Suite. Its value is 500 bottle caps (although it will probably be more around 700-800 for your player). The Jukebox will play whatever station was last activated on your Pip-Boy when activated.

The Jukebox won't work at Tenpenny Tower until you've boosted GNR's signal, and it will be hard to hear in your Megaton house until you boost the signal as well.

There is no real purpose buying it, other than for the aesthetics, since your Pip-Boy 3000 also works as radio.
