Next connect a wire to the aerial between the variable condenser and the stator and connect this to one post of a .0005 microfarad fixed condenser, then connect the other post of this with the grid of the detector and shunt a 2 megohm grid leak around it.
Now connect one end of the secondary coil to one post of a .001 mfd. variable condenser and the other end of the secondary to the other post of the condenser. Shunt 1/2 to 2 megohm grid leak resistance around the fixed condenser and then connect the second post of the variable condenser to one terminal of the detector tube filament.
For this set you require: one variocoupler; two variometers; one .001 microfarad variable condenser; one .0005 microfarad variable condenser; one 2 megohm grid leak resistance; one vacuum tube detector; one 6 volt A battery; one 200 ohm potentiometer; one 22-1/2 volt B battery; one .001 microfarad fixed condenser, and one pair of 2,000 ohm headphones.

Next connect one post of the .0007 mfd. condenser with one of the terminals of the detector filament; then connect the other post of this condenser with one post of the .0005 mfd. variable condenser and the other post of this with the grid of the detector, then shunt the megohm grid leak around the latter condenser.
