A Phoenician is a negative impedance load.
http://www.diyaudio.com/forums/chip-amps/302190-30watt-class-phoenician-amplifier.html
Here ,the Phoenician loads -RL/2 . It measures the output current and provides the same to the load , doubling the output power , decreasing the output impedance and subtracting the even order harmonic distortion with it's own.
Each mosfet has it's thermal drift compensation of 4mv/C° to be mounted upon it with thermal compound after scraping off the writings . A piece of metal holds the sensors planked by the screw of the mosfet.
The input transformers I used are the following

The heat sink measures 20cm wide 10cm high 3.5cm thick made of 21 wings cools the mosfets 72C° at 30C° ambient .
It has a soft, noiseless start at 1.2A with offset 200mv , within a minute it is 1.3A with offset 70mv and passes gradually in 7 minutes to definitive 1.4A. It shuts down in silence.
This amplifier has H₂O compound (colorless , odorless , tasteless transparent) sound , makes it first choice amp for proximity studio monitor.
Distortion and frequency responce (50khz) are mainly due to the input transformers.
