Well, if it has anything to do with "The Final Countdown"(a decent movie...the best was ogling Katherine Ross, of course), then it would probably be either some kind of retro=radio of some kind or some type of surge supressor...a gigantic magnetic storm/vortex caused the ship(the Nimitz, I believe) to go back in time. If I have to choose one of the two, it'd be the Retro Radio.
Now, all I have to do is figure the 2150 part out....probably two SET tubes with a total of 150 watts/side....naaaaah, couldn't be.

RR could also have something to do with Rail Road?...amp rails?
