I have the same reaction reading the title of this topic. My father kept one and every time I visit them, I remember the times when we listen to the radio for news and the times when my father would sing along to the music on the radio.
I don't think too many people buy these antiques with the intention of actually using them; the value is in the fact that they are no longer produced, and so rare. People do the same with gaming consoles, cameras, household items, and so on.
I used to own a music shop that bought and sold used gear and taught music lessons.
I bought an antique radio for my store window and you'd be surprised at the number of people who wanted to buy it simply because it brought back fond childhood memories.
