We produced a replica of the original Rife Beam Ray device based on publicly known general specifications. We found several available schematics, but in our case they proved inadequate and sometimes contradictory. In practice, the classical Hartley-type LC oscillators used in the original Rife Beam Ray clinical devices proved somewhat unstable and sensitive to capacitive coupling with the sides of the metallic enclosure. To facilitate production, we modified the existing schematics in several places based on our calculations. As a result, we achieved an electrically stable and reliable design.
UPDATE: PRODUCTION HAS BEEN DISCONTINUED
Building the Rife Beam Ray device
Our replicas are intended exclusively for exhibition, educational and research purposes. They are not medical devices.
The carrier wave is adjustable from 2.2 to 3.6 MHz and is fairly stable, aside from thermal drift in the oscillator circuit. Crystal-controlled oscillators, or even modern active RC oscillators, can achieve better stability and precision, so there is plenty of room for improvement in this section of the device. Modulating signal with this modulator input circuit is limited to 80–100 kHz. However, with improvements to the input circuit, modulation should reach at least 150 kHz or more. That said, we found this type of thermionic valve gating circuit lacking, especially when using a sinusoidal wave as the modulating signal. The performance of the gating circuit can be improved, but other more efficient types of active semiconductor circuits could and, in our opinion, should be employed in that role. We found the modulator amplifier schematic suggested by Aubrey Scoon particularly unstable due to significant design flaws, and after working with it for a while, we significantly changed the circuit design and achieved very reliable operation with Vpp up to 88 V for frequencies up to 100 kHz.
The circuit is thermally stable, and the output transistors run completely cool when mounted directly on the experimental device chassis. We have done extensive experimental work on the device’s internal design and the electrical and physical behaviour of different circuit elements. During those experiments, we observed several interesting effects that correspond to our observations and measurements with the Lakhovsky Multiple Wave Oscillator replica. If we hadn’t had initial problems with publicly available designs, we would never have been forced to make so many measurements and physical observations. In the end, initial problems can lead to interesting observations and new conclusions.
It helps to have a small collection of old radio parts from the thermionic valve era, so modifications and observations are done in a matter of hours or, at worst, in days instead of weeks and months. Using proper test and measurement equipment also proved to be of utmost importance. In the past, we have designed several Rife-type devices with more complexity and capability for signal processing and mixing. However, we found some of the observations made on this classic type of plasma antenna-based Rife device to be invaluable for future advancements in this type of technology.

None of our work on this type of technology would have been possible if it had not been for the late Aubrey Scoon, who got us interested in this type of technology in the early 2000s. His electrical designs were sometimes odd and somewhat finicky, but without his enthusiasm and energy, this field of electrotherapy research would not be where it is today. He was rather forthcoming in our conversations and has helped a lot. Thank you, Aubrey.
