On list is one piece of dual low noise 2N5566 J-FET, best to be used for differential input of audio amplifier or input stage of power amplifier or other audio applications. In particular they are the no.1 choice to be used in building a Goldmund type preamp or power amp differential input stage.
They are exceptionally good at low dc drifting because the two fets are closed binded together and sealed in a hermetically-sealed TO-71 package ( metal can package) for life-long durability.
The listing is for one piece.
