What is a "Kit/2" (half-kit)?
This is a new concept to the DIY world. With the goal of keeping customer cost low, a half-kit contains only the customized parts that are not available off-the-shelf. All remaining components are to be purchased directly from another supplier. Half-kits contain:
User Manual - A complete description of the product including assembly instructions, parts lists, and schematics.
Circuit Board - A blank (no components) circuit board upon which the product is built. Circuit boards are the backbone of my products as they provide super-easy assembly and eliminate wiring mistakes. They cleanly implement the intellectual property of a design.
Drill Guide - A highly accurate 1:1 guide printed on paper that makes marking hole placement a snap. No need to bother with rulers and protractors.
Why a "Kit/2"?
Inventory is expensive. The cost of stocking parts, kitting them, and then reselling would obviously require a hefty markup in price. My solution is to provide the customer with a parts list where they can go directly to the original supplier. No markup. Also, many customers like to build amplifiers using their own preferences for capacitors, resistors, chassis, and tubes. The half-kit concept insures you do not have to pay for parts you won't need. Similarly, if you already have a stock of parts on hand, you do not have to pay for anything you don't need.
The idea is to save cost. This concept eliminates middlemen and provides extreme flexibility.
Why not a "Kit/2"?
If you truly want to go it alone, you can. I offer up my intellectual property (schematics and parts list) as free downloads. You may use them for personal use, not for anything offered for sale. Copyrighted material, etc.
So why invest in a circuit board?
