Perhaps as a selling point, I suspect that the general public would buy a 6 tube radio over a 5 tube radio expecting better performance. Several manufactures at the time offered "6 tube" radios that departed from the optimum design, to save a few bucks in manufacturing. Remember those "10 transistor" radios that used many of them as diodes?
