It has a diameter of 6-1/4 inches, a height of 7-7/8 inches and a length of 9-3/8 inches, and it costs $11.00. The Aerial Condenser. This condenser is made up of three fixed condensers of different capacitances, namely .0003, .0004 and .0005 mfd., and these are made to stand a potential of 7500 volts.

The parts you need for this set include: one variocoupler; one .001 microfarad variable condenser; one .0005 microfarad variable condenser; one .0007 microfarad variable condenser; one 2 megohm grid leak; one vacuum tube detector; one 6 volt A battery; one 6 ohm, 1-1/2 ampere rheostat; one 200 ohm potentiometer; one 22-1/2 volt B battery; one .001 microfarad fixed condenser, one pair of 2,000 ohm headphones, and a variometer.

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.

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.

Now connect one end of the secondary coil, or rotor, of the variocoupler with one post of the .0005 mfd. variable condenser and the other part to the grid of the detector tube. Connect the other end of the rotor of the variocoupler to one of the posts of the first variometer and the other post of this to one of the terminals of the detector filament.
