I was thinking the same thing. They look pretty similar. BTW Great Job on it resto Bill. Enjoyed looking at some of your battery building videos. I had one of those little red Motorola portable was like a 6" cube the front flipped up exposing the very pretty chrome grille think it was a model 5A1 Anyway that thing drove me nuts! Every time I'd get it working go to put it back in the cabinet it would quit. Seems like when we are working on any of these sets with 1.5v tubes they are very sensitive to a lot different things that their 6.3v big brothers aren't.Stray capacitance, any sort of poor connection, or even just a little dirt can really stop these little guys from working. Lower voltages, Lower currents and higher operating impedance's all spell everything's got to be right in order for it to work well. And trying to find some of these bugs that will drive you crazy
