I repaired TV's when I was in high school to support my ham hobby. I would pull suspect tubes and take them to the drugstore to check them and buy replacements. Later I found a portable B&K tube tester and then ran to Radio Shack to get tubes. Does anybody remember the gold plated pins on the Realistic brand tubes? They had a lifetime warranty.
