Context

Country: North America
State/Province: Unknown
Period: 1959 through 1972
Canada: Unknown
Function: To evaluate the current gain of bipolar transistors.
Technical: When Transistors began to replace tubes, the technicians and test set manufacturers assumed they would perform similar to tubes and have a finite lifespan; thus, the need for a transistor tester to replace the tube tester. Since transistors do not age like tubes, the transistor tester quickly became obsolete. (From Notes tab)
Area Notes: Unknown
