Lakhovsky Multi Wave Oscillator: Functional Heavy Duty Replica

Posted by:

Historically, Multi Wave Oscillator devices were devices physicians used for electrotherapy from 1930’s into late 1980’s 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.

Recently we were commissioned to produce a functional replica of the historical Multi Wave Oscillator, a device also refered to as Multiple Wave Oscillator or MWO of Dr. Georges Lakhovsky. The heavy duty Multi Wave Oscillator replica that we produced is in every significant aspect (frequency content, output power, signal envelope, phase reversal, concentric antenna etc.) virtually identical to the historical Multi Wave Oscillator Model 2 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 ebook “The Lakhovsky Multiple Wave Oscillator Secrets Revealed (3rd edition)” by Tony Kerselaers and Bruno Sacco.

Multi Wave Oscillator devices have been mentioned in literature for decades, however, the technical details and specifications were largely unknown and in the speculative domain. There has 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 to 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 ebook “Biological Effects of Exposure to Multiple Wave Oscillator Fields” by Tony Kerselaers that reveals how Multi Wave Oscillator affects the living organisms.

Production Requirements

In the production of this functional replica, there were several requirements that we needed to meet. Click on a section to jump to it in text:

  1. Device was to operate within the historical specifications (i.e. transmitter and reflector frequencies and their relationships, output levels)
  2. Split-ring resonator antennas were to be produced according to historical Multi Wave Oscillator BV2 model (2nd generation model)
  3. All components were to be able to reliably operate for several hours daily with MTBF (Mean Time Between Failure) exceeding 10,000 hours
  4. The device was to be able to operate both on 230 V / 50 Hz as well as on the 120 V / 60 Hz electrical utility systems
  5. Sturdy and durable enclosure with modernised design was to be used
  6. Safety was to be increased compared to the historical originals
  7. EMI/RFI interference introduced into electrical mains was to be minimised
How the Requirements Were Met

1. Device was to operate within the historical specifications (i.e. transmitter and reflector frequencies and their relationships, output levels)

High voltage resonator coils

In order to ensure produced signal similarity to the historical devices we made 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 preciseness and compactness of the windings. After resonator coils were made, they were tuned in compliance to the historical specifications. In this particular case basic resonant frequency of the transmitter secondary was tuned to ~906-910 kHz, while the resonant frequency of the transmitter primary was tuned to ~840 kHz. On the reflector side the resonant coil was tuned to ~880 kHz.

2. Split-ring resonator antennas had to be produced according to historical Multi Wave Oscillator BV2 model (i.e. 2nd generation model)

Split-ring resonator antennas were made according to historical Multi Wave Oscillator BV2 model specifications. We opted to use silken ropes harness identical to the original in order to retain as much authenticity as possible compared to the historical original. Although it may appear that silken ropes are susceptible to charring when exposed to effluvia, in our tests we proved they can easily withstand extreme conditions of being exposed directly to stable RF discharges (something never encountered in normal operation of the device).

3. All components were to be able to reliably operate for several hours daily with MTBF (Mean Time Between Failure) exceeding 10,000 hours

In order to ensure reliable operation of the device during prolonged periods we had to carefully choose the key components:

Capacitors

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 more compact single components like pulse rated Strontium-Titanate capacitors, in our experience such components have a tendency to gradually heat up during prolonged periods of operation with consequent loss of performance and increased decay of the dielectric.

Instead we opted to use so-called Multi-Mini Capacitor (MMC) type of design. Simply said, many smaller capacitors are connected in such arrangement which divides voltage stress and heat losses among individual components. In our cases we used high impulse rated film capacitors manufactured by WIMA. Additional high quality bleed resistors with appropriate voltage rating of 10 kV per device were used to ensure fast discharge of the capacitors when the Multi Wave Oscillator is not operating.

Custom made Multi Wave Oscillator capacitors

In this particular case we used total of 48 individual capacitors per MMC. In total, we used 96 capacitors in the entire Multi Wave Oscillator primary tank circuit with net voltage rating of the capacitors at ~26’000 Volts. Thus, nominal voltage rating is about 400 % higher than the maximal output voltage rating of the high voltage transformer used to charge capacitors. In such way we provided extremely large margin of capacitor’s reliability and longevity of the components.

The capacitors were all connected with thick copper bus bars which are connected together both mechanically and by soldering. Symmetrical arrangement of the capacitor strings ensures that all branches are equally stressed during discharge cycle.

After MMC was put together, it was placed in the ABS enclosure and vacuum-potted by high voltage rated epoxy compound. The placement of the entire arrangement into plastic enclosure allowed for easier placement of the capacitors into the base unit enclosure.

High voltage, radio-frequency chokes

High voltage, radio-frequency chokes are used for suppression of transients that may damage the windings of the charging high voltage transformer. Although the secondary windings of our custom made high voltage transformer was tested to 25 kV DC we decided it was better to further reduce risk of damage to it.

HV RF chokes were made according to technical specifications of the historical Multi Wave Oscillator BV2 model and proved to be quite efficient in transient suppression.

Spark gap

Spark gap that was used was the improved version of the historically used V-type spark gap. While there is nothing unusual about the way this type of spark gap operates (quenched spark gap) its unique geometry provides more precise adjustments of the gap between wolfram (tungsten) electrodes. Additionally, by using circumferential surface as discharge area it is possible to use thinner wolfram electrodes that are normally available on the market. In that way user is able to easily buy replacement electrodes, which are essentially the only spare part in the entire Multi Wave Oscillator.

In order to improve 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 burn out of the Bakelite. We also modified electrode holders so it is now possible to replace the electrodes without the need for disassembly of the spark gap. The electrodes we choose to use are standard 3.2 mm types which can easily be bought in welding equipment shops.

Safety spark gap

Safety spark gap

Safety spark gap is another component that is used to protect secondary winding of the high voltage transformer by discharging transient peaks into the grounding. In this case we designed easily adjustable spark gap with three spherical electrodes, one of which is grounded. It proved to be quite efficient in operation and in normal operation it doesn’t heat up significantly.

Forced cooling, ozone venting

We also had to improve cooling of the electrodes and their holders if the device were to be able to operate for prolonged periods. We opted to use forced air cooling with introduction of two large industrial axial fans. Their combined air flow throughput of ~320 m3/h proved to be crucial during longer periods of operation because it kept the temperature stable at ~50-55°C.

Components testing

Components testing is one of the crucial parts of the manufacture of any functional replica. In order for the devices to be able to operate reliably for many years, all components have to be able to withstand extreme operating conditions found in normal operation. Based on practical experience, we usually produce components that can withstand even the most extreme conditions that will never be encountered in normal operation.

In case of this heavy-duty functional replica of historical Multi Wave Oscillator our primary concerns were voltage and current ratings of the key 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 assembled, tuned and tested all components we run it in the normal operating conditions until we were satisfied that the entire device operates stable, with no insulation breakdowns nor overheating of the components.

Then we take the entire testing to the extreme and pushed the input/output power to ~280 % of maximal power encountered in normal operation of the device. At that point all components were put under severe stress for period of over 15 minutes and they behaved flawlessly. Essentially it means that when working under normal conditions even for prolonged periods of time the expected service life of all the components should easily exceed operating 10,000 hours.

It is worthwhile noting that during such extreme operating conditions a curious behaviour was observed with stable RF discharges forming between 1st and 2nd split-ring resonators. It is not something that was observed previously because nobody before drove Multi Wave Oscillator to such extremes.

4. The device was to be able to operate both on 230 V / 50 Hz as well as on the 120 V / 60 Hz electrical utility systems

High voltage transformer with adjustable power limiter

High voltage transformer is used to increase voltage from electrical mains voltage of 230 V (or 120 V) to high voltage necessary to charge primary tank capacitors. Although we considered using electronics power supply due to its low weight we decided it would not be a good solution in this case due to ageing of its components which would shorten total service life of the Multi Wave Oscillator which can easily be measured in decades.

After some consideration, we decided to add extra functionality to the original design in order to improve 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 same specifications as in the original device. To achieve that we made custom made the HV transformer with improved characteristics – selectable output voltage and linearly adjustable current limiter. In that way we married the best of historical solutions with a different, more modern approach.

It also gave us the opportunity to improve and modernise the HV transformer performance and increase its maximal ratings. This particular transformer was made on 1000 W core with vacuum potted insulation and additional layers of Mylar to increase its maximal rating which was tested to 20,000 V AC and 30,000 V DC. Additional adjustable magnetic shunt was introduced into the transformer magnetic core in order to limit output current in pretty much linear fashion (continuously) rather then just by three settings.


5. Sturdy and durable enclosure with modernised design was to be used

Enclosure requirements:

  • Full-sized cabinet
  • Sturdy enough to survive many years of service
  • All of its elements grounded to ensure high level of safety
  • Enough net surface of ventilation openings
  • Modernized design
  • High quality finish

We decided to use galvanized steel in combination with aluminium in order to achieve as homogeneous grounding of the enclosure as possible and to modernise the design. Although using 2 mm thick steel plates adds to the total weight of the device, it also makes a very sturdy chassis. All of the enclosure elements were entirely plasticised with texture finish in order to protect steel parts from corrosion and to improve overall appearance.

Control panels were made from thick brushed aluminium plates which were then anodised to improve panel’s resistance to oxidation and corrosion due to moisture and sweat. Markings of the control panels were made by laser engraving and acid etching to ensure their longevity and prevent possible fading of the letterings.

6. Safety was to be increased compared to the historical originals

Grounding

All elements of the enclosure were later connected by thick grounding wires to get homogeneous electrical surface which makes better Faraday cage (less EMI/RFI interferences) and virtually removes electrical shock hazard for the user. Although all internal components are non-flamable, steel enclosure also virtually entirely removes the risk of possible accidental fire spreading to surrounding area.

Enclosure has one service door with a keylock to ensure easy access to the internal components. Additional micro-switch prevents accidental powering on of the device when the access door is opened. In order for user to be able to observe operation of the main spark gap we added a small observation window. The observation window consists of glass layers and ultra-violet light filters in order to prevent possible damage to eyesight.

Quality of grounding plays a significant role in the operation of the Multiple-Wave Oscillator because physical ground essentially closes electric circuit. It directly affects efficiency of the Multi Wave Oscillator and great emphasis was put on the quality of the grounding by Dr. Lakhovsky himself in his writings and notes. Later measurements performed by Tony Kerselaers and Bruno Sacco on historical devices confirmed it in their reverse-engineering report.

These oscilloscope screenshots made with analyser tool described in the reverse-engineering report clearly show different behaviour of Multi Wave Oscillator grounded by the typical electrical mains grounding and dedicated RF (radio-frequency) grounding.

Common Mode Using Dedicated RF Grounding (Optimal)
Differential Mode Using Dedicated RF Grounding (Optimal)

Historical Multi Wave Oscillator with non-optimal grounding
Common Mode Using Common Electrical Mains Grounding (Non-Optimal)
Differential Mode Using Common Electrical Mains Grounding (Non-Optimal)

The signal envelope is much more pronounced in case of dedicated grounding as it should be if we compare it with the envelope measured at the historical device. So, the better quality of the grounding means better historical accuracy and efficiency of the Multi Wave Oscillator setup.

Cabling

Cabling was additional factor to take into account because other than their electrical characteristics they also had to be ozone resistant and, when possible, to provide additional element of safety. So, for internal cabling we used double insulated silicone cables for electrical mains and HV transformer output sections. However, we chose to use high performance cables with insulation not resistant to ozone so we provided silicone sleeving to protect them from the ozone induced decay.

External high voltage cabling was of special concern due to the fact that it is functionally a part of the primary tank circuit. It means that in case of failure of the cable insulation there is an increased risk of accidental electrical shock which can be very dangerous due to large amount of energy stored in high voltage capacitors.

Multi Wave Oscillator spark gap and chokes cabling

We opted to use heavy duty coaxial cable with its electrical shielding connected to electrical ground. In that way, in case of insulation failure electrical current goes directly into grounding thus providing high levels of safety for the operator.

We also produced custom made high voltage connectors with thick PTFE (Teflon) insulation to match the coaxial cable and to provide uninterrupted shielded high voltage line from Multi Wave Oscillator base unit to the transmitter section.

7. EMI/RFI interference introduced into electrical mains was to be minimised

EMI/RFI suppression was another thing to be considered. Virtually all high voltage resonant transformers produce strong voltage transients which may be injected back into the electrical mains installation. It means that interferences may adversely affect other devices connected to the electrical installation. In order to suppress strong transients we used high-quality, medical grade filter which proved to be quite efficient in its role.

Enclosure acting as a Faraday cage

Additional radio-frequency interferences are produced by the spark gap. The most suitable way to shield the environment from RF interferences was to use entirely grounded metallic enclosure. In this replica we used 2 mm thick galvanised steel plates, all of which were additionally electrically connected together by thick silicone insulated cables. Most of the RF interferences produced by spark gap are thus removed due to the enclosure behaving as a Faraday cage.

In addition

Multi Wave Oscillator Custom Hand-Held Implements

Additional hand-held implements were regularly used with historical Multi Wave Oscillators in order to focus high frequency displacement currents to particular treated areas. In fact they are described in historical notes as essential part of the procedures used by Dr. Lakhovsky and Dr. Vassileff.

Hand-held implement 2

In this case, we were commissioned to manufacture replicas of the original hand-held applicators, so we used original historical specifications described in 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.

In Conclusion

In the production of this heavy duty Multi Wave Oscillator replica all the requirements were met and even exceeded. The device is in every significat way virtually identical to the historical Multi Wave Oscillator Model 2, operating both on 230 V / 50 Hz as well as on the 120 V / 60 Hz electrical utility systems and strictly within the historical specifications. This heavy duty device was tested under extreme conditions and its MTBF can easily exceed 10,000 hours. The modern sturdy enclosure and double insulated silicone cables for electrical mains and HV transformer output sections ensure increased levels of safety and minimised EMI/RFI interference.
