We produced a replica of the original Rife Beam Ray device based on publicly known general specifications. We found several available schematics which in our case proved to be inadequate and sometimes contradictory. In reality, classical LC oscillators of Hartley type used in the original Rife Beam Ray clinical devices proved to be somewhat unstable and somewhat sensitive to capacitive coupling with sides of the metallic enclosure. To facilitate the production we modified the existing schematics on several points based on our calculations. As a result, we achieved an electrically stable and reliable design.
Building the Rife Beam Ray device
The carrier wave is adjustable from 2.2 to 3.6 MHz and is somewhat stable aside from thermal drift of the oscillator circuit. Crystal controlled oscillators or even modern active RC oscillators can achieve better stability and precision, so there is much room for improvement in this section of the device. Modulating signal with this particular modulator input circuit is limited to 80 – 100 kHz. However, with some improvements in the input circuit modulation should be sufficient to at least 150 kHz or more. That being said we found this particular type of thermionic valve gating circuit to be lacking and especially so when using a sinusoidal wave as a 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 modulator amplifier schematic suggested by Aubrey Scoon to be particularly unstable due to significant design flaws and after playing a while with it we significantly changed the design of the circuit and achieved very reliable operation with Vpp of up to 88 V for frequencies up to 100 kHz.
The circuit is thermally stable, and output transistors are running completely cool when mounted directly on the chassis of the experimental device. We have done much experimental work with the device internal design and electrical and physical behaviour of different elements of the circuit. During those experiments, we observed several interesting effects corresponding with our observations and measurements done with Lakhovsky Multiple Wave Oscillator replica. If we have not had initial problems with publicly available designs, we would never have been forced to make such a significant number of measurements and physical observations. So, in the end, it turned out that initial problems can lead to interesting observations and new conclusions.
It helps to have at your disposal a small collection of old radio parts from 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 already designed several Rife-type devices of more complexity and capability of 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 of this type of technology.

None of our work on this type of technology would be possible if it were not for 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.
