That's silly....we're talking about building ham radio amplifiers here, one
of a kind in most instances. We're not concerned with specification
variability, production yields, tolerance stack-ups, etc. This line of
reasoning may apply if you're Ameritron or Alpha but not if you're a
hobbyist wanting to build an amp for personal use.
