Rife Machine & Frequency Generator
In the early rife machines, the process involved the output from the amplifier which was fed into a simple ‘antenna tuner’ similar to those used today by industry, amateurs and a few CB operators. The tuner was designed to transfer as much power from the output (807) tube to the Rife tube as possible. The tuner output was used to excite or drive the Rife tube.
The Rife tubes consist of a hollow glass tube filled with an inert gas. There is a metal electrode at each end of the tube for connection to the outside world. The vacuum tubes were ideally suited to driving the Rife tubes for the reason that tubes like the 807 could be ‘abused’ without too much of a problem. You see, the Rife tube takes at least 700 volts to strike, but once it is struck or ignited, the Rife tube only needs about 350 volts to maintain its arc.
Since the tuner only transfers maximum power to the Rife tube a finite time after it has been struck, the 807 is not delivering its full power to its load. This causes the tube voltages to exceed the normal amount by perhaps three to four times until the Rife tube has fully struck. The vacuum tubes like the 807 were extremely tolerant of this sort of abuse.
The output of the super regenerative oscillator is amplified with a power amplifier tube such as the famous type 807. Some early photographs of the Royal Rife machine show the easily identifiable outline of this tube. These tubes were capable of putting around fifty watts of power into the Rife tube, which was and still remains the source of the healing, flashing (interrupted) light, working on the principles of DrRife frequency generator.
Only a few people made rife machines over the past decades, until relatively recent times when there has been a resurgence. However, vacuum tubes have been very hard to get, and some interesting alternatives have been produced in the recent years.
Notably, the Royal Rife machine is a combination of CB radio as the radio frequency source and a transistor power amplifier and commercial tunerto deliver power to the Rife tube. These machines worked very well, but lacked in the long term reliability in the earlier versions. These units are still popular today.
There were and continue to be a number of rogue machines as well, by less reputable manufacturers wherein the construction was/is poor, and without having a genuine square wave output to the tube.
