1958 Harlie TR-10

Micro-table / coat pocket radio, thermosetting plastic cabinet
5 x 3 1/8 x 1 1/2 inches / 127 x 79 x 38 mm
Four transistors (2N359, 2N362, 2N436, 2N483, + NEC SD46 diode), superheterodyne circuit
One tubular 9-volt battery
Distributed by Harlie Transistor Products, Inc., New York
Likely manufactured by Shirasuna Denki Mfg. Co. Ltd. (Silver)

The finest thing about this radio is its glossy super-hard thermosetting plastic cabinet in a completely unique caramel color. And like many other transistor radios having a low transistor count, the TR-10's face identifies the model simply as, "All Transistor."

The transistor types noted above come from the label on the inside back cover of the set, not from the transistors themselves: The four transistors used here are all early GE-type "pinch top" top hats, yet none of them has any markings — the only thing distinguishing one transistor from another here is that each is a different color: red, gold, silver, pale green — that's really sweet and pretty unusual, and it makes me wonder if I'm missing something here in identifying these!

Another transistor model distributed by Harlie utilizing this same cabinet was the five-transistor TR-659 (see photo below) in a stunning bright red color. Other Harlie cabinet colors included black (very glossy) and white. The 4-transistor Harlie TR-10 shown here shares a nearly identical cabinet (and probably also circuit and chassis) with the Stantex TR-4, a model stated on's Stantex page to have been manufactured by Shirasuna Denki Mfg. Co. Ltd. (Silver).
