Letter Tube Numbers XXL vs. 7A4 etc

Actually, it is (or I should say WAS) 42 to 50 mc. What you see on your Philco's dial scale is something which was called "channel numbers." This was obtained by dropping the leading 4 and the decimal point, leaving the last two numbers. Hence, 42.1 mc became 21 on the dial, 49.9 mc became 99, etc.
