Its very good that your looking into the great George Lakhovsky's work and product called the Multiple Wave Oscillator. George is my favourite old time healer and its a shame he isn't known as widely as Royal Ramond Rife. Georges results were fantastic for Terminal patients as was William Reich and Royal Rife's.
The best M.W.O would be one using proper copper tubed coils that are properly MUSICALLY tuned like Lakhovsky's machines. If you can find one of these and if its pumped by 2 seperate Tesla coils then it should be a fantastic machine properly better than Lakhovsky's limited (due to year) machine. The only problem with coil machines is the fact that they need calibrating and lineing up correctly for the proper performance to be had. Also the best machine would utilise car batteries for the safest possible action with the body instead of the mains supply.
Dan Dial INVENTED the Molecular Enhancer and makes the best version around of this device. Its priced about $1300 and many people are very happy with the machine and theres some great cases with Cancer remission. This runs off the mains and basically your right inbetween the 15,000 volt neon sign transformer shielded from the current via what is now fibreglass and plastic. You hold a large neon-filled bulb as Argon is very stimulating especially to the Lymph. I must tell you though that these type of machine can cause very harsh Herxheimer reactions (healing) they work very quickly especially the Violet Ray systems. A vintage Violet Ray has serious power and the reactions can be very hard if your not cleansed. The results I've seen with the Violet Ray was so quick its almost amazing in some cases.
I hope you get a M.W.O soon and keep us posted with your findings.
