I will take some time over the next while to bring the Phase Liear to the forefront of the line up. I have the privilege to own a few. One is the second of the line. I have taken the time to fully understand these beasts and tweaked them to what I feel is now the best of the best. I am not finished my quest as I have plane to improve them further.
There seams to be mistery and misnomers abound when ever people talk about this amp
I am not surprised by that it’s partially due to it being a rare bird. Not may were made, less than two thousand units, over about two years of production. It was only sold in a quassi complimentary state. Ev has said one may have been made as full Complimentary.
so to start up here is a post I found on the internet:

Awesome beast amps. I used to fix the heavily-modified D500's as used for the Pink Floyd Wall shows; racked and flightcased, two to a rack, power transformers relocated to the bottom of the rack and hooked in by 8-pin plugs to the amps, retapped to give + / - 128v instead of 120v on the rails.
These would produce 1kW/chan into 2 ohms nominal. The output stages had to be biased bang on for maximum sweetness, but this could (and often did) cause a couple of blown output transistors - if the biasing had been set when cold and it drifted up when hot, pop. Apart from the usual misuse from the engineer du jour.
Magic sound, though. Power, dynamics, clarity and an output damping factor that had the loudspeakers by the balls, I never heard anything back then that could remotely come close. MOSFETS sound horrible to me to this day (well, once they've got hot and pinchy), BJT just owns them and the Dual 500 does it in spades. They were my babies for a couple of years and I still cherish the memories.
