As the title says, this is a set of two YAMAHA HC2700 amplifiers (with DUPLEX rack case, patching panel, power tap, pre-wired, ready to go). Fully functional, no blown bulbs, no crackling. Fanless and quiet. With this, you can drive up to eight speakers of the Electro-Voice SX300 class at a considerable volume (8Ω 270W/ch, 4Ω 350W/ch). And all from a single wall outlet (power consumption is less than 800W for both units. Even using four HC2700s at full power on a single 100V-20A outlet, the breaker won't trip). Shipping is only via cash on delivery. No price reduction, please. These are becoming difficult to obtain. If anyone needs them, please take this opportunity.
