1947 Trav-Ler Radio with a Surprise!

1947 Trav-Ler Model 5002 6 tube radio - with some modifications.
Had this old thing since I was about 12, bought from a garage sale. It was all original, and it worked, but I decided to replace all the capacitors anyway, just to make sure it'll continue working for years to come, and I added something to make it relevant for years to come.
