Ultra LD Mk.3 135W Class AB Audio Amplifier Kit
2 x 135W Ultra LD Mk.3 Class AB Audio Amplifier Kit 240V
(SC July ‘11) An improved version of the K 5151 Mk. 2 edition. It features less than half as much distortion at frequencies of 2kHz or above. It also boasts much improved thermal stability & flatter frequency response. Produces incredibly low levels of distortion even at high power outputs. The class AB design runs much cooler than genuine class A amplifiers, yet performance has not been sacrificed. It produces 135W into 8Ω or 200W into 4Ω with distortion levels around 0.006%. Heatsink is not supplied. We suggest the H 0536 diecast heatsink for a professional finish when mounted in a case. (SC Mar-May ‘12) A stunning low distortion, high power stereo amplifier designed for superb performance in any 2 channel audio system. It delivers 135W RMS per channel into 8 ohms (or 200W RMS into 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 & flatter 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.

(SC November ’12) Class-D amps are commonplace amongst consumer equipment, yet have been hard to reproduce reliably in kit form, until now! This rugged and reliable Class-D audio amplifier produces up to 250W into 4Ω. Its high efficiency, high power design is ideal for building into a larger audio amplifier design. Low distortion <0.01%. Based on the IRS2092 audio amplifier chip. SPECIFICATIONS Power output: Efficiency: Signal to noise ratio: Total harmonic distortion: Frequency response: Power requirements:

12V 20 Watt Amplifier Module Kit (SC May 2010) Amplifiers which run from 12V DC generally don’t put out much power and they are usually not hi-fi as well. But this little stereo amplifier ticks the power and low distortion boxes. With a 14.4V DC supply, it will deliver 20 watts per channel into 4 Ohm loads at clipping while harmonic distortion at lower power levels is typically less than 0.03%. Price Each
