Many Tektronix scopes from the 1960's contain '''Germanium transistors''', e.g., [[OC170]], [[OC171]]. | Many Tektronix scopes from the 1960's contain '''Germanium transistors''', e.g., [[OC170]], [[OC171]], [[2N2207]]. | ||
These transistors are prone to failure. One particular failure mechanism is the growth of tin whiskers from the tin-coated inside walls of the transistor case. | These transistors are prone to failure.
