CN3165 Clapp Crystal Oscillator

Clapp Crystal Oscillator circuit using 2N3904 NPN transistor with single 5V power A popular circuit, used in SAMPO CN3165 Frequency Counter and so on. In real world, this circuit works fine, but it will not start to oscillate because it is too ideal and stable and will not start in simulation. Toggle (On then Off) the [Start] button to add a stimulus to start oscillation.
