The problem with the theory that the modifications were made during the war is that older types like 27s, 24s, 47s, etc were easier to get then the newer octal types. The hardest tubes to get during the war years were the 150 ma AC/DC tubes. Also if it were a case of just trying to keep the set running during a parts shortage why add a magic eye tube and socket?
