GB-4000 / M.O.P.A. Combo

GB-4000 Sweep/Function Generator & M.O.P.A. Oscillator Amplifier Combo

 

The 195-watt M.O.P.A. Amplifier works with the GB-4000 in both "Audio" and "Radio Frequency" modes. Users can run all "Auto Channel" frequency programs up to 20 Million Hertz. This is a true breakthrough, as there is not another plasma tube instrument on the market that has this capability!

 

  • 2026 version including latest upgrades/software (Rev. D8). 

  • The M.O.P.A. amplifier is 20 Megahertz capable with a variable built-in carrier frequency of 2.2 to 3.7 MHz and is a 1930s/1950s replica. When connected to the GB-4000 it is capable of outputting 8 frequencies simultaneously.

  • A full 2-year manufacturer's parts and labor warranty.

  • FREE lifetime technical support and professional training consultation.

  • The Plasma Ray Tube antenna with reflector and stand is not included but is sold separately by another vendor for $395 + shipping.

  • A GB-4000 Accessory Kit also available from another vendor for $165.99 + shipping. The kit includes a complete guide, Universal Frequency List (262 pages) for the selection and use of specific resonant frequencies, 4 stainless steel electrodes with terrycloth sleeves (which are plugged into included wires) to use optionally with the GB-4000 by itself, when needed.

  • We will facilitate these two separate vendor orders for you if requested.

DISCLAIMER:  We purposely don't refer to our high-RF instruments Rife Machines, or a Rife frequency generator, like many other device companies do. Dr. Royal R. Rife specifically stated that he didn't want his name put on any machine because "some people" might use his name to promote or sell their own frequency machines. Those companies who respect his wishes don't call their machine a Rife Machine. The function generator and amplifiers shown on this website are sold as electronic test equipment. Many people and home researchers would like to experiment with the full effects of Dr. Rife's original frequencies. The GB-4000 / M.O.P.A. system is very capable of running ALL of Dr. Rife's original and proprietary frequencies, even those in the millions of Hertz. Those high radio frequencies may be emitted without any 'frequency splitting' (or mathematical division) to obtain a lower, and a much less effective harmonic of the original Rife frequencies. Information disseminated on this website is public knowledge for educational and research purposes only.
