Now you can get the best of both worlds, Analog and Digital with the vintage replica of the MOPA (Master Oscillator Power Amplifier), equipped with the original tank circuit of all 1930's oscillators and driven by the digital GB4000 which holds thousands of programmed frequencies!
Having scoured systems all over the world we can confidently say this is the most powerful generator of it's type available boasting over 190 watts of power output.
Our MOPA Amplifier is the only vacuum tube driven amplifier of it's type driven by the historical 812a vacuum tube. The pioneers of this technology used the 812a, an "air-wound" coil (no metal core) and a variable capacitor for tuning. These three components are the "tank circuit" which the majority of 1930's radio oscillators used.
Updated with modern electronics the MOPA / GB4000 system gives you what you're looking for:
Hands free operation, non-contact frequency delivery
Outputs all the original 1930's - 1950's frequencies (All from one easy-to-use system.)
Frequency Counter built-in on front panel
Massive 190 Watts of Power Output
Full 2 year parts and labor warranty
Best in class telephone support (look at our reviews!)
While our competitors boast of a 30 foot broadcast range we prefer to educate our people about the inverse-square law which means the further away you are (even our competitor's 100 watt lower powered system) the less power you'll be getting.
In fact you could use a meter and "see" the power from the MOPA up to 1/4 mile away! Does that mean it's effective at that distance?
Because the MOPA / GB4000 system is a plasma broadcasting system you won't be locked-down with cables or electrodes. In fact you'll have the flexibility to move around while the frequencies pulse from the plasma tube throughout your environment. This allows you to do other things while the frequencies are pulsing giving you much more flexibility.
The ability to rest, read, watch videos or movies, etc. makes the MOPA system much more convenient than non-plasma tube systems.
Plasma tube has 5 foot cables for ease of positioning without being tied to the MOPA
Reflector is directional but can be easily removed for whole-room broadcast

190 Watts Boosted Power Output!
You won't find a higher power output than the MOPA. Some of our competitors with fancy looking systems are running only 35 to 100 watts but with the MOPA you get the full power you're looking for (190 Watts) in a radiant plasma broadcasting system.
The frequencies are broadcast through a noble gas filled tube made out of pyrex glass. This is a specially designed antenna that can handle the power of the MOPA while still being compact.
Plasma also brings in the unique plasma induction. Plasma is considered the 4th state of matter; solid, liquid, gas and the 4th state of plasma which is an ionized gas.
The Plasma State means the electrons on the atoms of the gases are no longer bound to the nucleus of the atoms. This creates a vibratory effect outside the plasma tube.
This is what we call "Plasma Induction" and the key to a plasma tube driven broadcasting system like the MOPA and GB4000. This is why it is operating "hands free" and it's also why the full 190 watts is needed!
Of course you can also control the power output and turn it down if needed. It's all under your control so you can use it the way you see fit.
The heart of the analog output is the vacuum tube driver. Without that you can't replicate the original output.
MOPA offers the only system with an easily adjustable RF Carrier delivering a level of precision not possible with any other system out there. Range is 2.2 to 3.8 MHz
Both Audio and RF outputs and multiple waveforms allow easy replication of the historical frequencies.
The GB4000 is the control interface for the MOPA GB4000 system and it's been perfected to be both versatile for the advanced user (gating, waveform selection, etc.) as well as simple to use for any newbie.
Full numeric keypad for easy access to 880+ standard programs and over 1000 channels for custom programming
No mysterious hidden frequencies keeping you in the dark like our competitors!
Extensive programming features using keypad or windows software for advanced users but computer not needed for normal operation!
We also provide exclusive training videos in both DVD and online format, custom programs and the best support (see our reviews!) that you won't find from any other dealer. All you have to do is give us a call and you'll get a taste of our top notch support.
No additional generators needed at extra expense like our competitors.
Runs up to 8 frequencies up to 40kHz or 2 frequencies over 40kHz
With all the extra power of the MOPA it's sufficient to run many frequencies at once without missing out on adequate power like our competitors.
In addition to top notch support rest assured your system is made to last and backed by a full 2 year parts and labor warranty and expected to last many more years to come with economical updates available (some free less shipping!)
Order right now with confidence! Try it out for 60 days and if it doesn’t work for you, you’ll get your money back (less 10% to cover our costs in essentially renting you a brand new system)! No questions asked, you can get your money back!

Important: When you purchase a GB4000 it is a good idea to also purchase an accessory kit from Revive LLC which is currently $142 USD. No additional cables are needed those come with your GB4000.
Please note: The Plasma Tube Assembly with reflector and noble gas filled tube is sold separately from a 3rd party and is currently $375 plus shipping. That includes all the cables needed to connect it to your MOPA. The 2" diameter and 14" long pyrex glass tube is sufficiently designed to handle the massive power delivered by the MOPA and we don't recommend other potentially dangerous plasma tubes for use with your MOPA. Contact us and we will share the resource where you can purchase the plasma tube assembly.
