What Are The Keys To Magnifier Success?
Power Conditioning
Input power must be conditioned in any magnifier using non-shunted transformers! The simple neon sign transformer can be used as is and requires no conditioning. This would place an upper limit on non-conditioned AC line power of under two kilowatts. We found these smaller magnifier systems were superb concept demonstrators, but the same power in the hands of an expert two coil builder could yield almost equivilant results. The magnifier really comes into its own at powers over two kilowatts! The best transformers are large potential transformers or small distribution transformers under 15KVA rating. We found the best control of the input energy was secured by mixing both resistive and inductive ballast in series with the power transorfmers primary winding. The resistance is often well under 1 ohm and the inductance under 5 milliHenries. These values are typical and will vary from system to system.
Without power conditioning, the main transformer will saturate and power will be wasted. If pure inductance is used, a see-saw action of the transformer and ballast can result in some frightening current exchanges between the two and uneven operation will result. Using only resistive ballasting, a large amount of energy is lost in heat. With a ballance of the two, energy is saved, smooth operation is secured, and very long run times are possible at high powers.

Input Voltage
Only one rule applies here. The voltage must be as high as possible!!! Watch it though, many new and unfamiliar problems occur above 20, 000 volts. Corona and flashovers become a real system gremlin. The average coiler has little experience in this area and new techniques must be developed, not to mention the expense of extremely high voltage pulse capacitors. Tesla never ran his large systems with voltages over 20,000 olts more than enough times to destroy bottles within his capacitors and realize his materials were not up to the task. This is verified in the Colorado Springs Notes. Do not let anyone tell you differently. With reduced capacitance he could experiment above 30,000 volts, but shunned the practice. The desirablity of such high input voltages will become apparent with the discussion of the driver system.
Spark Gap
A crucial component in a working magnifier is the spark gap system. Tesla's gap system in Colorado was very poor indeed and just barely sufficed for experimental purposes. He had trouble with it at the elevated input voltages during a few experiments. The Corums have led the way here, in that they tell us that the spark gap must quench in some tens of microseconds. This is beyond the casual coiler's gap inventory. Special gap construction is a must!
The secret is to not strain the gap. Break the arc up into as many individual arcs as possible to spread the energy out evenly over as many surfaces as possible. Also include a rotary in series the chain somewhere. This is done to give a precisely controlled break rate and dwell period.
Any series gaps must be either vacuum or compressed air cooled within plenums. We have designed a special series arc rotary quench gap that can actually quench faster than required (also a bad condition). It is all in the operation and handling of the arc that the magnifier really sings. This is where the casual coiler is separated from the experimentalist. The gap is the bottleneck in any magnifier system.

Primary Tank Circuit
We tried many different primary tank circuit configurations and found Tesla's original Colorado Springs circuit to be the best operationally, but the most difficult to balance and adjust, (see figure 2). Tesla really knew his stuff.
The spark gap shouls appear acros the power transformer's high voltage secondary and two absolutely matched and balanced capacitors should then be placed in the tank circuit connecting each side of the gap to the primary leads. Due to the critical need for tight coupling and conveying rapid rise time energy pulses to the primary coil, very short, fat low inductance connections must be used throughout. Tesla was forced to use a regulating coil to tune his primary tank circuit. This was terribly ruinous to his efficiency but was unavoidable with his physical configuration. You must not use such a device!!!!
In smaller systems, we use a number of easily accessable turns, so tune and tap directly to the primary turns. Tesla's primary turns were one or two turns fully insulated and were neither accessable nor tappable. He paid a terrible price in reduced coupling coefficients as he allowed more off axis inductance to creep into his system. Fully, as much as 40% of his energy was lost in some experiments due to this one factor. Tesla commented that the system ran best with all turns "out" in the regulated coil. I don't doubt it one bit either.
The capacitors used for this work must be pulse types and have the lowest possible internal inductances so as not to rob system energies by creating off axis inductance or dissipating energy in the dielectric. We have termed Tesla's tank circuit "the Tesla equidrive circuit". One must be capacitor rich in order to tune the circuit over a broad range with capacitance. Telsa was able to do this over a limited range in 1899 by adjusting the number of bottles in one tank on each side of his capacitor bank. The modern amateur is best advised to to tap the primary coil directly. Naturally, all of the classic primary tank circuits will work but the equidrive circuit seems to yield the most power.
There is grave danger in this circuit! The series capacitors pose a life threatening hazard after power shutdown. There is a good chance, depending upon the point during the AC cycle when power was removed, that the capacitors will retain a dangerous charge. If this circuit is used, do not tune or thouch the primary circuit until both capacitors have been discharged!
