grid circuit controlling still greater fluctuations of audio- 1 THE REGENERATIVE RECEIVER 131 frequent plate current which causes the telephone receiver disks to vibrate more violently, producing louder sounds. The amount of regeneration in any case will depend upon the particular vacuum tube in use and the circuit in which it is employed. Polarity of the tickler coil. In using as a tickler coil, the secondary winding of a loose coupler or any winding which cannot be rotated, connection to the ...plate circuit may be made in such a way that the pulsations of current fed back, "degenerate" instead of regenerating the incoming oscillations. For regeneration, the pulsations of current from the plate circuit must pass through the tickler coil hi such direction that their electromagnetic effect will be that of building up the incoming oscillations which are passing through the grid inductance. If the reverse connection has been made, the effect of the fed back pulsations will be to oppose and decrease the effect of the incoming oscillations in the grid circuit.
