Hi Wayne,Thanks for the information. And, I appreciate your looking through the Emerson archives you have on disk in the attempt to identify this model.
I can tell you this about that 43 tube. The socket has 43 stamped on it and appears to be original like the others in the radio.
But, like you mentioned. Who knows what this radio has seen? That's part of the fun of it, right? To speculate who has listened to this radio in the past and what was heard on it.
All the best,
Mark
