(Silicon Chip Magazine Mar-May 12)A stunning low distortion, high power stereo amplifier designed for superb performance in any 2 channel audio system. It delivers 135WRMS per channel into 8 ohms (or 200W RMSinto 4 ohms). It utilises two of the K 5154 Mk. 3 amplifier module kits, plus power supply board, toroid, speaker protector kit, input and pre-amp boards - all supplied in a stylish 2RU all metal chassis. Silicon Chip have vastly improved the performance of the amplifier modules over the Mk. 2 edition. It features less than half as much distortion at frequencies of 2kHz or above. It also boasts much improved thermal stability &latter frequency response. Produces incredibly low levels of distortion even at high power outputs. The class AB design runs much cooler than genuine class A amps, without sacrificing performance.Important Note For Kit Buyers:This product is supplied in component form and requires soldering, drilling, and assembly. We recommend users are familiar with at least basic electronic principles and have the ability to solder.Features
