I have been working all morning on above circuit. Internet shows several videos of above being used but not getting it to run on EveryCircuit.

Change LED for speaker to 8 ohm resistor. No connection from 47K ohm resistor to 555 pin #7. Connect from 555 pin #3 wire going between 47K ohm resistor and 10 uH inductor coil. I get steady 6 to 10 Hz. output.

Slow simulation speed to 4ms/s to show output to speaker 2.5 kHz. Also, can remove 10 nF to pin #5 of IC.
