I am building an excel spreadsheet of just commonly used audio tubes so i can print my own booklet of settings for my Hickok tube tester so i don't need to sort through pages and pages of tubes for TV, and ham radios and the like. I know many high end amplifiers used uncommon tubes. I am just looking for tube numbers commonly used. the normal 6L6 run of the mill stuff. here is my list so far. what am i missing??? these are not in any sort of order.
