Actually those sets were designed properly. They used a floating B- line, which is not connected to the metal cabinet. It does use an isolating capacitor from the B- to the cabinet and the antenna coil.
BTW, the two and three tube sets are a TRF, where the four tube is a short superhet, which is a good DX machine with about 100 feet of antenna.
