I have this small Table top Emerson U4B in my collection. It was made in 1935 (according to the info in Steins Volume 1 on page 93) According to Stein's, it is an Ingraham cabinet too. It has 4 vacuum tubes + a ballast. The tubes are: 6D6, 6C6, 43, & a 25Z5. It's size is 10.5 " wide by 7.5 " high and 6 " deep ( + knobs ) . It weighs 7 pounds. Has a 5" diameter speaker with a field coil too.
Because of my lack of a new ballast, I had to modify the power supply to get it operating correctly. I now have this set completley restored & operating fine too. I do have 2 pictures of my set that I can upload when you modify the information on this model.
