In 1962, Zenith restyled the Royal 50H and produced the model 50K which was virtually unchanged. It again was offered in black, white, tan, red, and charcoal. It is compact in size at only 2 ½” wide and 4” tall and weighs only 7.7 ounces, but the six transistor chassis puts out an impressive 135 milliwatts of clear rich tone and operates on two common AA batteries. The cost new was $19.95
Here is a nice one for your collection. Clean inside and out, the cosmetics are outstanding and it plays as it should and produces a rich sound.
