How difficult is it to build the DIY kits?
My DIY kits are intended to be approachable for anyone who is comfortable using small hand tools and a soldering iron. You do not need experience with electronics or ability to read a schematic. My instructions are extremely thorough, with illustrations or photos and step-by-step instructions to take you from start to finish. I also include a very detailed explanation of the circuit and how it works, so you will not only build the amplifier, but will learn how it works (or at least however much you want to learn!)
Some of the components are rather small and require working in little spaces, so some physical dexterity and attention to detail are important! Soldering takes a little practice if you have never done it before, but it is a skill nearly anyone can do. If you are the impatient type who doesn't like to read directions and just wants to plug it in, then buying a fully assembled amplifier might be better for you! But if you have some time and focus, and want the satisfaction of seeing your own work come to life in amazing high fidelity sound, then a DIY kit might be a perfect project.
