MAGNIFIR.TXT The Tesla Magnifier circuit here shows one of several possible tank circuit configurations. Which tank circuit is employed is not really important until very high break rates (over 1200 BPS) are obtained from the rotary break. High break rates are desired, as they increase the amount of power that can be processed by the circuit. When these increases are obtained by using faster, more sophisticated, rotary breaks; the tank circuit configuration shown delivers significantly better performance. This diagram is intended to show the uncoupled end resonator. The circuit uses close coupling between the primary and secondary coil. This close coupling gives a much higher efficiency transfer of energy between the two coils. The end resonator (or "Extra- coil") is base fed by transmission line from the top of the secondary "driver" coil in the circuit.
