One more thing: The #47 trick was Zenith's own recommendation, straight from the horse's mouth so to speak. ISTR that no radio so modified has ever been known to burn up a(nother) power transformer. Keeping the 6X5 in the radio as intended also keeps the voltages correct, as a voltage drop through the tube would have been factored into the design. A diode has no voltage drop.
