I would have to find my date code sheet, and right now I honestly do not know what happened to it. I seem to recall that the letters used between 1930-1935 or 36 when they switched to the OPUS code were not in alphabetical order.
Philco globe tubes were made as late as early 1933, but just how long, I don't know at present. I'm at work and all of my data is at home.
Chuck, do you have anything?
