Physical ObjectDescription
The object is an unknown germanium device embedded in a yellow plastic substance. On one side there is a threaded post. On the other side there are four contacts that have been cut short.Per Jack Ward, Transistor Museum - "Early to mid-1950s. The case material for this unique semiconductor is typical of experimental devices from the early 1950s, produced by such pioneering transistor companies as Bell Labs/Western Electric, RCA and GE. The structure of the device suggests that this might be a multi-diode, with a common screw-type lead shown at lower left, and four individual diode leads shown at lower right. Further electrical tests would be required to positively identify the actual semiconductor type. Extremely rare – this is the only known example."
