Now connect one end of the secondary coil, or rotor, of the variocoupler with one post of the .0005 mfd.
The condenser used in the secondary coil circuit has 14 plates and this is equal to a capacitance of .0004 mfd.
Likewise connect the other loading coil in one side of the closed, or secondary circuit between the variable .0007 mfd.
Now connect one end of the secondary coil to one post of a .001 mfd.
Next connect the plate of the tube with one end of the .001 mfd.
