I am interested in building an amp kit, but many of them cost as much as buying a prebuilt amp. The main reason I am curious about amp kits is for learning circuitry rather than the fun of putting it together. I am wondering if putting amps together has really taught you fellas how the amplifiers work and what the components do, or if they were more like just putting things together according to directions, and not really getting an understanding of the amps circuitry? Would I get better knowledge through the many 'explanation of tube amps' books out there, or through putting together a kit? I'm not really interested in putting together a 'model' if I'm going to be following instructions and not learning, if that makes any sense.
