Gato Perfect Symmetrical Amplification
The Gato Audio TwinFET
The Gato Audio TwinFET amplifier is named from the design using two perfectly identical FET transistors that ensure perfect sonic timing, almost unlimited power and a perfect symmetrical high voltage swing. The TwinFET technology is sonically far superior to designs typically only focused on delivering voltage and current - not a perfect symmetrical time domain. Vacuum tube amplifiers use identical tubes in the output.
Tube amps can be designed with a single tube for positive swing and a single tube for negative swing. These amps have similarities to the TwinFET except for limited power.
To supply more power, output tubes are paralleled. This again creates a problem because of the difference between the tubes in the choir. Tubes have a finite life and start to deteriorate from the beginning. The problem is the deterioration curve is not the same on each output tube.
