I have one of these radios...I think the 1st 12DT8 may be for FM RF amp and AFC and the second one FM mixer and oscillator. On the single tube FM tuners one triode in the 12DT8/12AT7 tube is usually the RF amp and the other triode half the mixer/oscillator. I think mine has a schematic on it so I can double check what the functions are.
I have also seen this same radio under the Masterwork brand.
