As you can see this is a really small radio. I’m in the process of restoring it. It’s a t.r.f. Of a four tube midget radio the funny thing is it is a 1938 . I have about 30 radios in my collection it all started when I was ten I love the little baby ones .
It's cute. 4 tube? Interesting. Probably be difficult to find room in that, but I added Bluetooth to a slightly bigger 6 tube radio I have. Tune it to the top of the dial, and it clicks a switch and goes beep-boop and then you can pair your phone.
