1500 watt power conditioner/distributor with receptacles to power up to four power amps(total of 1200 watts for the amps) and up to six additional receptacles that power up to 75 watts each. The unit is highly regarded and built very solidly. It is in excellent condition with factory box. New it cost $850. Very conservatively rated at "8". It can be mated in a system with the Audio Power Industries Power Enhancer 1 and API PW-V I am also selling. Thanks for looking. My price is more than fair, so no "low-ball" offers, please. Please email any questions.
