Usually these 2 tube units have a detector (27) and an oscillator (24) for output.
While not exactly the same, I restored one of these and tested it in a rare Northland console last month:

My conclusion was that this was an interesting accessory that was not very practical for everyday use and that had been demonstrated by an early repair in which they had fixed the radio and simply unhooked the SW adaptor. But they are fun to play with.
