The circuit is given above and needs very little explanation. It operates from a 10 volt supply and regulates to about 4.5 volts. This is used to excite the tuned circuit VC1/L1. The tapping is about 3% of the total number of turns of L1. A 6% L1 tap is coupled to the control input if the LM317T regulator chip and BINGO - It "hoots". You can draw WATTS of power from a 12% tapping of L1.
