Both are right the first tubes 12SA7, 12SK7 etc. are octal and were used in the 1940's. The 2nd set, 12AV6, 12BA6 etc. were the more modern 7 pin tubes used in the 1950's. Both groups have been called All American Five. It's best to look in your radio to see what tubes are used. There are other variations such as 35L6GT & 35C5.
