MOPA Amplifier Historical Tube Powered 1930’s Style Plasma Tube Power Amplifier Now Boosted to 190 Watts!
Now boosted to 190 Watts of RF Output! The MOPA Oscillator/Amplifier along with the GB4000 Frequency Generator is the perfect combination. This is the only machine designed with the 1930's style electronics including a vacuum tube inside.
You'll love this addition to your GB4000!
- The M.O.P.A. or Master Oscillator Power Amplifier uses the gas filled tube radiant method of outputting frequencies from 1 to 20 million Hertz.
- Improvement over modern solid state equipment which uses low voltage and high current output - the M.O.P.A. uses a high voltage and low current design for much better efficiency (runs cooler so you can use it for extended time without overheating. This is the same method used in the 1930-1950 equipment.
- Allows input of the full range of GB4000 frequencies
- Now comes with a built-in frequency counter so you can accurately set your desired carrier frequency.
- New maximum frequency range: When using the "RF Mode" 1 Hertz to 20,000,000 Hertz.
- Compact design - 10.5" Wide X 17" Long X 10" High
