I'm interested in getting into this hobby more, and wondering what parts most of you keep "on hand" for various projects? I'm interested in building amplifiers mostly, but eventually other things like DACs etc. While I understand the basic process of ordering a BOM for a project, from reading lots and lots here on the forum I get the sense that people have accumulated a good "stock" of piece parts through their time in the hobby. For someone just starting out, what would you recommend? I don't want to get in to a project just to find I need some $.20 part which I have to order. Is there a set of basic values for piece parts that one should have at hand?..or is the variety of components just so vast that there's no point in even trying? Say I wanted to spend $200 to fill a parts bin with resisters, caps, screws, standoffs, hook up wires, fastons, etc, what would I order?
