8/13/2023 0 Comments Motorola all transistor radio![]() ![]() The antenna was housed inside a plastic "carrying handle" many times bulkier than a simple brass wire handle such as what the Zenith Royal 500 or Emerson 888 employed. Motorola's solution was much more in-your-face in appearance than was GE's - nearly bordering on the ridiculous - and also much more memorable. GE solved this problem on its own metal-cabinet radio, the extruded aluminum P-715 and P-716 models, by placing the ferrite rod in a discreet and unassuming black plastic housing cut into the top back of the radio's cabinet - you hardly even notice it's there. All these sets have a metal cabinet - so where does the ferrite rod antenna go? Motorola's first transistor radio, and the smallest of its "antenna handle" coatpocket radios.

The 56T1 has a painted speaker grille, something not all that common among US transistor radios. Another problem was plastic mold, something found fairly often on the 7X23E and several other early Motorola models as well. The cabinets of some of Motorola's early transistor radios seem to have been more fragile than those of other manufacturers of the time, and for several reasons - this 56T1 has a nickel-plated cabinet coated with a gold-color lacquer that has turned out not to stand the test of time very well: on many examples the lacquer has worn away in places, leaving the nickel color exposed. Interestingly, on this example (see the chassis photo below), each Texas Instruments transistor has been over-stamped with a Motorola "M" logo, either on the top of the transistor or on the face bearing the TI logo. It uses a standard 9-volt battery and it has a PC board. It's very likely that production began in late 1955 and the 56T1 became available for sale in early 1956.
