Eliot, thanks for the link. These are the instructions I used when I rebuilt my Knight. I had lost the link when my computer hard drive died. Mike (Morzh) is right, you can get by without a cap checker, (and a bunch of other stuff as well) but if one grabs your attention, go for it. As a tech in the profession for years, I tried different test instruments and eventually put what I used most right in front of me, the rest went on the top shelf, and seldom used equipment under the bench. It doesn't hurt to have some seldom used stuff since you could run into a weird problem, in which you may be glad you have it. Eventually, you will settle on YOUR favorite equipment after you gain experience using it (or not).  There is always Ebay if you find you don't like something at all.
