I've gfot the single band model of that set it's a good player on batteries. The B battery current is about same as a transistor set @ 12ma. Filaments are 200ma. I used 4D cells in parallel and work out fine. Not sure how long they would last maybe 10-15hours. I get the cheap ones from the $store. The major plus is that since your not plugged into the ac line it doesn't pick a whole lot of interference. Bit like a humongous wooden portable.
