Good low-noise audio NPN transistors for headphone amplifier
(1/1)
TheUnnamedNewbie:
I'm designing a (silly) headphone amp as a project. I would like some output NPN transistors for the final stage. I get about 1W of dissipation in the device and 500 mA max collector current. Preferably available in through-hole since this project will be bread-boarded and all that.
Don't need a device that has a complementary PNP.
Zero999:
Low noise isn't important for the output stage, since it's a unity gain emitter follower.
How about the BD135?
