Im Gegensatz zu Radioempfängern für kommerzielle und/oder militärische Zwecke und den frühen Empfängern für Morsezwecke nennen wir hier Radio bzw. Rundfunkempfänger.

Wir unterscheiden hier ebenfalls nicht, ob mit Röhren bestückt, hybrid, mit Transistoren oder/und ICs.Radio or Tuner

The Lafayette 5-tube TRF for Short Waves "Wild World" (in catalog 1931 page 60 as Wideworld - in one word) needs a separate power unit with a UX-280 tube. This "Wild World" power pack costs $ 18.00 separate. For addl. $ 5.00 it can operate from 25 cycle mains. The Wild World receiver is supplied with the coils for operation from 14 to 115 meters wave length. Extra coils per pair cost $ 3.24: "Brown" 9-15 m, "Blue" 115-200 m, "Orange" 200 - 360 m, "Yellow" 350 - 550 m. For the 20 and the 20 m band there are band spread coils, $ 3.82 per pair. The tubes cost $ 8.88. The "Wild World" chassis only is $ 45.50. It has a push-pull output. The cabinet is separate for $ 4.00. See details and summaries in this catalog.
