Re: Any good amp kits out there?
Step-by-step instructions do take a lot of time and effort to put together and still some may not agree with the way they are done, and IMHO, aren't really needed. I'm not trying to be pedantic but if you have to be told/shown how to solder a terminal and a wire together, maybe you shouldn't think of building an amp in the first place and start with something simpler first to build up your confidence and experience. There are, of course, subtleties that you have to mind but they should be researched first anyways. If you're building a tube amp, there's a lot of things you have to understand first, not just know where to connect.
Weber does supply a layout which tells you pretty much where to connect everything, except the grounding pattern, which you have to research yourself.
If someone's just starting out, there's a lot of research and reading to be done before going headfirst in an amplifier. Some places, such as Tubedepot, do have step-by-step instructions on how to put their kits together and are available on their sites for free. If you're researching your first build, downloading a few and looking at how they do things is a good idea even if you don't intend on buying their kits...soldering is soldering and laying out wires is laying out wires.
