This compact amplifier module kit packs a surprising punch for its size! Whilst keeping many of the low distortion characteristics of Silicon Chips popular Ultra-LD amplifiers, it can achieve 60W into 8 ohms or 100W into 4 ohms with a distortion level below 0.0008% at 1kHz. And less than 0.008% all the way up to 20kHz. That's way better than "CD quality" sound. Utilises a pair of NJW1193/4 output transistors for fantastic audio performance from a module measuring just 64mm wide - meaning you can pack in more sound into less space in your design. Supplied with all components, heatsink not included (we recommend one H 0580 heatsink per module) or if using as a multi-module amplifier choose a single large heatsink for your case. For power supply capacitors we recommend 2 x R5601.

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.

Why buy an Altronics Kit?
Altronics kits are premium do-it-yourself projects designed to be assembled with ease. However, basic electronics knowledge and soldering skills are essential to construct our kits. A difficulty rating is provided to help determine if your ability is sufficient to build the kit project. Please note, once assembly has been commenced we are unable to honor any warranty claims. Please see the full details here.
