I used it in an audio preamp I built as a hobby project around 1970, and I used it in an analog programmable-gain amplifier I designed around 1985. It's still available from Mouser for 10 cents each, and is still made by Fairchild. www.fairchildsemi.com/ds/2N%2F2N3819.pdf Also, it's first on the list of devices in LTSpice! Paul

Gm is 45 mS and noise is 0.8 nv/rthz. There's nothing else like it. John
