This is a high quality stereo power amplifier, producing 200 watts plus into a 8 ohm speaker load and 300 watts plus into 4 ohms impedance. The unit was made for the American market, so is a 115 Volt unit. It does however come with a high quality English 1200 Watt Retro look step down transformer which has been tested on the unit at full output on an analyser with no voltage drop. There is a Plinius IIc preamp available with matching glass top at an extra cost, should the purchaser require one.
