The wise-cracks about left-handed tools (although there are some) reminded me of tech school in the USAF in the '60's when you really learned electronics and how that 'durned electronical stuff worked'.
One of the my instructors sent one of the more naive students (no, not me)down to the school secretary to get a fallopian (sp?) tube. And then went FLYING out the door to get him, cause that E2 YESSIR type was GONE! smile John C. (Not Garand)
Oh, shoot I forgot! For you folks born after about 1960, instead of transistors and IC's, 'electronical' equipment used to use 'tubes'. These were glass jars with pins and neat little metal plates and filaments, and pieces of screen, stuffed in the open end and then sealed. Operated on 100-500 volts, or more. John C. again

When I was young, I was Liberal. As I aged and wised up, I became Conservative. Now that I'm old, I have settled on Curmudgeon.
