I don't intend to run the radio very much, just for demonstration purposes. Now that the cardboard is all cut and ready, all I will have to do is make new battery packs for the inside, and that is relatively easy... just an evenings work; so if I have to do the job every 3 years or so, no big deal. It would be very easy to make a suitable power supply that will fit in the radio also, made to the same dimensions as the original battery, but I would have to make a small cut in the radio's back on one edge for the cord to come out. Right now the back as well as the rest of the case is perfect, and I'd rather leave it like that.
