Historically, Lakhovsky Multi Wave Oscillator devices were used for electrotherapy by physicians from 1930s into late 1980s in Europe. Nowadays, with the advances in research of bioactive effects of pulsed electric fields and radio-frequency signals, a renewed interest has developed in historical devices which have been proved beneficial for some types of diseases that are, even today, hard to cure.
We produce Lakhovsky MWO heavy duty replicas of superior quality that are in every significant aspect (frequency content, output power, signal envelope, phase reversal, concentric antenna etc.) virtually identical to the original Multiple Wave Oscillator model BV2 that was originally produced between 1933 and 1940. Technical specifications that we used as a guide were based on detailed information found in the comprehensive reverse-engineering report of the three historical Lakhovsky oscillators published in an eBook “The Lakhovsky Multiple Wave Oscillator Secrets Revealed” written by Tony Kerselaers and Bruno Sacco.
Lakhovsky Multi Wave Oscillator devices have been mentioned in the literature for decades. However, the technical details and specifications were mostly unknown and in the speculative domain. There have been many notable attempts of deducing the design Dr Lakhovsky’s Multi Wave Oscillator based only on general descriptions. However, those were based solely on educated guesses and in many cases such designs significantly strayed from the original design, resulting in the devices of dubious bioactive properties. The most comprehensive practical and theoretical research on bioactive effects of Lakhovsky’s Multi Wave Oscillator and clinical treatment of various diseases is published in the eBook “Biological Effects of Exposure to Multiple Wave Oscillator Fields” by Tony Kerselaers that reveals how Multi-Wave Oscillator affects the living organisms.
Manufacturing Lakhovsky Multi-Wave Oscillator Heavy Duty Replica
In the manufacturing of the heavy duty MWO replica, the following requirements need to be addressed:
1. Operational requirements compliant with historical specifications (i.e. transmitter / reflector frequencies, their relationships and output levels)
1.1. High voltage resonator coils
To ensure the compliance of the produced signal to the signal generated by the original Lakhovsky MWO devices, we make acrylic coil formers which hold primary and secondary windings of the high voltage Oudin resonator. By machining the grooves on the surface of the former, we ensured the preciseness and compactness of the windings. After resonator coils are made, they are tuned in compliance with the historical specifications.
2. Split-ring resonator antennas compliant to the original Lakhovsky Multi-Wave Oscillator model BV2 antennas (i.e. 2nd generation model)
We manufacture split-ring resonator antennas according to the original Multi-Wave Oscillator model BV2 specifications. We opted to use satin silk ribbon identical to the original to retain as much authenticity as possible. Although the fabric may be susceptible to charring when exposed to effluvia, the tests proved it can easily withstand extreme conditions when exposed directly to stable RF discharges (something never encountered in the regular operation of the device).
3. All components able to reliably operate for several hours a day with MTBF (Mean Time Between Failure) exceeding 10,000 hours
To ensure reliable operation of the device during prolonged periods, we carefully choose the components:
Capacitors are the components that suffer most stress due to powerful and fast discharges they have to provide to the primary coil. Although we could have used smaller single parts like pulse rated Strontium-Titanate capacitors, from our experience, such components tend to gradually heat up during prolonged periods of operation with the consequent loss of performance and increase in the decay of the dielectric.
Instead, we opted to use so-called Multi-Mini Capacitor (MMC) type of design, i.e. many smaller capacitors connected in an arrangement which divides voltage stress and heat losses among individual components. We use the high impulse rated film capacitors, and additional high-quality bleed resistors with an appropriate voltage rating of 10 kV per device to ensure fast discharge of the capacitors when the replica is turned off.
We use 48 individual capacitors per MMC. In total, we use 96 capacitors in the entire Multi-Wave Oscillator primary tank circuit with the net voltage rating of the capacitors at ~26,000 V. Thus the nominal voltage rating is about 400 % higher than the maximum output voltage rating of the high voltage transformer used to charge the capacitors. In such a way, we provide a considerable margin of capacitors reliability and longevity of the components. The capacitors are all connected with solid copper bus bars which are connected both mechanically and by soldering. The symmetrical arrangement of the capacitor strings ensures that all branches get equally stressed during a discharge cycle. MMC is placed in the ABS enclosure and vacuum-potted by high voltage rated epoxy compound.
3.2. High voltage radio-frequency chokes
We use high voltage radio-frequency chokes for suppression of transients that may damage the windings of the charging high voltage transformer. Although we tested the secondary windings of our custom made high voltage transformer up to 25 kV DC, we decided it was better to reduce the risk of damage even further. HV RF chokes are made according to the technical specifications of the original Multi-Wave Oscillator BV2 model, and they proved to be quite efficient in transient suppression.
3.3. Spark gap
We manufacture replicas of the historical V-Type spark gap. To improve the smoothness of movement, we modified adjustment mechanism, and additional PTFE (Teflon) layer was added to prevent any possible charring of the underlying Bakelite which could lead to short circuit and Bakelite burn out. We also modified electrode holders, so it is now possible to replace the electrodes without the need for disassembly of the spark gap. The Wolfram electrodes are the standard 3.2 mm type which can easily be purchased in almost any welding equipment shops. Electrodes are the only spare parts in the entire Multi-Wave Oscillator replica.
3.4. Forced cooling and ozone venting
To be able to operate for prolonged periods, it is necessary to provide cooling of the electrodes and their holders. We use forced air cooling by two large industrial axial fans. Their combined airflow throughput of ~320 m3/h proved to be critical during more extended periods of operation because it kept the temperature stable between 50-55 °C. The fans also serve to vent out the excess ozone from the MWO enclosure.
3.5. Safety spark gap
The safety spark gap is another component that is used to protect the secondary winding of the high voltage transformer by discharging transient peaks into the grounding. We designed an easily adjustable spark gap with three spherical electrodes, one of which is grounded. It proved to be quite efficient, and in regular operation, it doesn’t heat up significantly.
3.6. Components testing
Components testing is one of the crucial elements in the manufacturing of any functional replica. All components have to withstand extreme operating conditions encountered in regular operation to ensure the device will serve reliably for many years. Based on practical experience, we usually use and produce components that can withstand even the most extreme conditions that would never be encountered in regular operation.
In case of the heavy duty replica model, the primary concerns are the voltage and current ratings of the critical components and their heating during prolonged periods of operation (high voltage capacitors, primary tank wires, spark gaps, high voltage transformer and high voltage resonators).
Once we assemble, tune and test all the components, we operate the replica in the usual working conditions until the entire device works stable, with no insulation breakdowns nor overheating of the parts. Then we push the input/output power to ~280 % of the maximum power encountered in the regular operation of the device. All components are tested under severe stress for over 15 minutes. It means that when working under normal conditions, even for prolonged periods, the expected service life of all the components should surely exceed 10,000 hours of operating.
4. Device operation on either 230 V/50 Hz or 120 V/60 Hz electric utility systems
4.1. High voltage transformer with adjustable power limiter
The high voltage transformer is used to increase voltage from electrical mains voltage of 230 V (or 120 V) to high voltage necessary to charge the primary tank capacitors. Using an electronics power supply would not be the right solution due to the ageing of its components which would shorten the total service life of the entire device which can easily be measured in decades.
We added extra functionality to the original design to improve the precision of adjustment. In historical Multiple-Wave Oscillator, HV transformer had one fixed output voltage and current limiter with three settings to set charging rate of capacitors, i.e. to set output power. We opted to make this functional replica more versatile while retaining the same specifications as in the original device. To achieve that we opted for a custom made HV transformer with improved characteristics – selectable output voltage and linearly adjustable current limiter. In that way, we married the best of the original solutions with a different, more modern approach. It also allowed us to improve and modernise the HV transformer performance and increase its maximum ratings.
This particular transformer was made on 1000 W core with vacuum potted insulation and additional layers of Mylar to increase its maximum rating which was tested to 20,000 V AC and 30,000 V DC. An extra adjustable magnetic shunt was introduced into the transformer’s magnetic core to limit the output current in a nearly linear fashion (continuously) rather than just by three settings.
5. Sturdy and durable enclosure with modernised design
- Full-sized chassis
- Sturdy enough to survive many years of service
- All of its elements grounded to ensure a high level of safety
- Enough net surface of ventilation openings
- Modernised design
- High-quality finish
We use galvanised steel in combination with aluminium to achieve as homogeneous grounding of the enclosure as possible and to modernise the design. Using 2 mm thick steel plates makes a chassis very sturdy. All of the enclosure elements are entirely plasticised with texture finish to protect steel parts from corrosion and to enhance its appearance.
Control panels are made from thick brushed aluminium plates which are anodised to improve their resistance to oxidation and corrosion due to moisture and sweat. Markings of the control panels are created by CNC engraving and filled with paint to ensure their longevity and prevent possible fading of the letterings.
6. Increased safety levels compared to the historical MWO grounding
All elements of the enclosure are later connected by thick grounding wires to get the homogeneous electrical surface which makes a better Faraday cage (less EMI/RFI interferences) and virtually removes electrical shock hazard for the user. Although all internal components are non-flammable, steel enclosure also almost eliminates the risk of possible accidental fire spreading to the surrounding area.
The chassis has a service door with a key lock to ensure easy access to the internal components. Additional micro-switch prevents accidental powering on of the device when the access door is opened. For a user to be able to observe the operation of the spark gap, we added a small observation window. The window consists of glass layers and ultra-violet light filters to prevent possible damage to eyesight.
Quality of grounding plays a significant role in the operation of the Multi-Wave Oscillator because the physical ground (earth) closes the electric circuit. It directly affects the efficiency of the Multi-Wave Oscillator. Dr Lakhovsky himself in his writings and notes put a strong emphasis on the quality of the grounding. Later measurements performed by Tony Kerselaers and Bruno Sacco on the original devices confirmed it.
These oscilloscope screenshots made with analyser tool described in the reverse-engineering report show different behaviour of the Lakhovsky Multi-Wave Oscillator grounded by the typical electrical mains grounding compared to dedicated RF (radio-frequency) grounding.
The signal envelope is much more pronounced in case of dedicated grounding, which is in accordance with the measured envelope of the original devices. So, the better the grounding quality, the higher the efficiency of the device.
The cables have to be ozone resistant and also provide an extra element of safety. For internal cabling, we use double insulated silicone cables for electrical mains and HV transformer output sections to protect them from the ozone-induced decay.
External high voltage cabling is functionally a part of the primary tank circuit, which means that in case of failure of the cable insulation there is an increased risk of accidental electrical shock. It can be very dangerous due to a significant amount of energy stored in high voltage capacitors.
Therefore, we use heavy duty coaxial cable with its electrical shielding connected to the electrical ground, which ensures that in case of insulation failure electrical current goes directly into grounding thus providing a high level of safety for the operator.
We use custom made high voltage connectors with thick PTFE (Teflon) insulation to match the coaxial cable and to provide continuous shielded high voltage line from Multi-Wave Oscillator base unit to the transmitter section.
7. Minimised EMI/RFI interference introduced into electrical mains
EMI/RFI suppression is another thing we consider. Virtually all high voltage resonant transformers produce sharp voltage transients which may be injected back into the installation of the electrical mains. It means that interferences may adversely affect other devices connected to the electrical wiring. To suppress sharp transients, we use high-quality, medical grade filter which proved to be quite effective.
The spark gap produces additional radio-frequency interferences. The most suitable way to shield the environment from RF interferences is to use the entirely grounded metallic enclosure. We use 2 mm thick galvanised steel plates, all of which are additionally electrically connected by thick silicone insulated cables. Most of the RF interferences produced by the spark gap are thus removed due to the enclosure behaving as a Faraday cage.
8. Multi-Wave Oscillator hand-held implements
Additional hand-held implements were regularly used with the original Multi Wave Oscillators to focus high-frequency displacement currents to specific treatment areas. They are described in the historical notes as an essential part of the procedures used by Dr Lakhovsky and Dr Vassileff.
We make replicas of the original hand-held applicators that comply with the original historical specifications described in the reverse-engineering report. The only detail that was modified is the use of polymer (plastic) grips instead of the original wooden ones. This modification doesn’t affect the function of the device, but it is in many respects superior, primarily in the sense of less weight, resistance to moisture and higher durability.
The heavy duty replica is in every significant way virtually identical to the original Multi-Wave Oscillator Model BV2, operating on either 230 V/50 Hz or 120 V/60 Hz electrical utility systems and strictly within the historical specifications. Tested under extreme conditions the heavy duty replica has an MTBF in excess of 10,000 hours. The modern looking and sturdy enclosure, double insulated silicone cables for electrical mains and HV transformer output sections ensure increased levels of safety and minimised EMI/RFI interference.
Please note: We manufacture replicas of historical devices such as the Lakhovsky MWO, and we guarantee that it functions and behaves exactly like the original device model BV2. We do not make or intend to make any claims whatsoever of possible bioactive and therapeutic effects. For a Multiple Wave Oscillator replica to operate safely, it is the user’s responsibility to ensure adequate electrical installations and grounding (earth). It is the responsibility of a user to observe important safety precautions and to comply with EMI/RFI regulations. No liability is accepted for any injury, loss or damage incurred by improper use of a Multiple Wave Oscillator replica.
