Does Not Apply

On auction is one piece of Toshiba low noise 2SK389-V dual FET, designed for audio application. They are best to be used for differential input of audio amplifier or other applications that requires tight thermal coupling. Two matched FETs were put into one package for best matching and thermal performance. The thermal drift of 2SK389 is much much better than two tightly matched 2SK170( though sadly to say 2SK170 also gone obsoleted).

2SK389 has been long obsoleted for years. These are used, pull out parts and measured to guarantee to be as functional as new ones. They are genuine, of course.

The auction is for one piece.
