I have read things about tungsten bulbs and its thermally controlled resistance. But what can I use for an electronics project will be builded on a breadboard. I searched for tungsten bulbs and all they were looking like regular size 100+ V lamps.
So what is the alternative in electronics level for amplitude stability of wien bridge oscillator?
p.s : don't know relevant or not but, the oscillator will be used in an auido project.
