M.O.P.A Amplifier
The new M.O.P.A Amplifier Plasma Tube Frequency Machine

M.O.P.A. Amplifier

The MOPA Combo Package includes:

• The GB4000 Frequency Generator. The most powerful, most capable frequency machine on the market.
• The MOPA Amplifier/Oscillator
• Connecting cables to connect your GB4000 to your MOPA Amplifier
• Operating Instructions Manual

Modern solid state circuitry uses low voltage, high current designs, to avoid the additional engineering and component costs involved in building the types of machines used in the 1930's and 1940's. The M.O.P.A amplifier/oscillator combines solid state design with analog vacuum tube technology to generate a high voltage, low current output. The ability to produce a high voltage, low currnet output to drive the plasma tube makes the MOPA, coupled with the GB4000 frequency generator unique in the market. And even with the advantages of vacuume tube design, it is still almost $1500.00 less than other comparable plasma tube machines.
