[QUOTE="handsome, post: 935423, member: 772"] Indeed there are but many devices out there and all are interesting....but good engineering requires that devices be fit-for-purpose. Choosing an appropriate device is actually very simple: first determine how much gain you need, then determine what kind of load (resistance [i]and[/i] capacitance) your device will be driving. The first requirement brackets the mu of your device, the second it's current capability and plate resistance. As Ampdog points out once you have chosen a device then consult its characteristic curves and be sure it is indeed capable of it's claimed parameters (and within it's dissipation rating) when used in your circuit.
