PHILCO "Surface Barrier" Transistor Paperweight (Mid to late 1950s)
Item #587
PHILCO was one of the biggest transistor manufacturers during the 1950's.
This clear Lucite paperweight features three unmarked PHILCO "surface barrier" transistors manufactured in the mid to late 1950's. The germanium PNP surface barrier transistor was invented by Philco in 1954 as an improvement to the alloy-junction transistor and the earlier point-contact transistor.
The PHICLO surface barrier high frequency transistor technology opened up the use of transistors for high-speed computers (replacing vacuum tubes) and was used in the first all-transistorized large-scale computer in 1957, the PHILCO S-2000 "Transac". PHILCO was later acquired by Ford Motor Company in 1961.
These types of PHILCO transistors would have been manufactured in PHILCO's Spring City, PA. facility for use in military mobile computers, industrial control computers, transistorized commercial computers like the "Transac", and radios.
The middle transistor has it's hermetically sealed top cap removed showing the transistor components inside.
Paperweight manufactured by Clear-Float, Inc. of Attleboro Mass.
In unused condition, Measures 2.5" wide by 1.5" deep by 2" high.
