This leads me to the first job on opening the box of parts. Mistakes of that kind are most likely because some parts have been misidentified, probably as a result of digging through an unsorted pile of parts. I think there is an idea amongst some builders that doing a complete inventory before getting out the soldering iron is time taken from building. Every part in a K2 has to be identified for its position: whether that is done rumaging through unsorted parts or retrieving from a sorted inventory, the time taken to find the part is just about the same. It might take a little longer noting in the manual just where the sorted part is, but building is much more enjoyable, at least for me, when I can fetch a part when I need it knowing exactly where it is. During the inventory, some parts can be identified by elimination and subsequent recognition of the markings on it. I use a set of partitioned drawers. During the inventory check, I identify and store the parts in a partition of a drawer and note in the manual the drawer number and the partition letter. Many parts can be mixed in the same space, such as 10 uF electrolytic capacitors and 220 pF capacitors. Certainly a 2N7000 in the same place could not be confused with either of the capacitors. It takes surprisingly few drawers and partitions to sort completely a K2's inventory so that retrieval is almost guaranteed to result in the correct part. Check again when taking the part from its indexed place and check that the location it is going to is its destination. Then pick up the soldering iron.
