PHILCO 2N353 POWER TRANSISTORS, 1950's

Germanium Alloy junction Power transistor, similar to the T1040 of 1956, giving 12 Watts of power. Using a TO27 package with flexible leads, with the actual transistor mounted inside the dome. Because the standard became the familiar TO3 package this devices life became limited, although in 2010 some of these are still being sold as replacement parts today. Joined presumably a matched pair.
