NOS SYLVANIA 2N95 GERMANIUM POWER TRANSISTOR Collectors Tube Radio. Condition is New in Box!! The Sylvania 2N68 and 2N95 were some of the first germanium power transistors available commercially, beginning in 1955. These were made with an integral finned heatsink to allow increased power output. Sylvania supplied both PNP (2N68) and NPN (2N95) transistors with similar characteristics, and this allowed substantial flexibility in circuit design, especially for audio circuits that did not require expensive or bulky transformers. The characteristics and suggested circuits for these transistors is well documented in the 1955 Sylvania booklet ” 28 Uses for Junction Transistors”. The Sylvania type 2N101 (supplied without a finned heatsink) is equivalent to the 2N68, and the 2N102 is equivalent to the 2N95.

Includes original case – missing top portion. Radio measures 4 1/4″ x 2 1/2″ x 1 LWH. Shirt pocket radio, thermoplastic cabinet 4 1/4 x 2 9/16 x 1 1/8 inches / 108 x 65 x 29 mm Six transistors (Sony, 2x 2T65, 2T73, 2x 2T76, 2T84), superheterodyne circuit One standard 9-volt battery Manufactured by Sony Corp. Japan Released in November 1958, the first truly mass-marketed Japanese pocket transistor radio exported to the US, several hundred thousand units involved – this and its seminal, multiple-award-winning cabinet design make it one of the most historically significant transistor radios ever produced. A small and slim radio that could easily fit into any shirt pocket unlike its “pocket” predecessors, such as the Standard SR. F22, Hitachi TH- 621 and Sony. TR-63, the TR-610 incorporated a round brass-rimmed speaker grille that was to become an iconic emblem of the pocket transistor radio. Because of its unprecedented number of units imported to the US, its timeless cabinet design and its relatively low price, the Sony TR-610 was to become the second nail in the coffin (after the Sony TR-63) for the US consumer electronics industry. The Sony 610 came in four cabinet colors: red, white, green, and black – I still think black is by far the color that works best for this set. Early versions of the Sony 610 had a gold-colored dial plate, and later versions had a silver-colored dial plate. In 1959 or 1960 a lower-priced, five-transistor version was released: the Sony TR-510. My descriptions and numerous clear pictures are absolutely ac curate and I do my best to be perfectly clear and concise.
