Probably one of the AA-5 type at a guess, every house had at least one and
the same 12AT6/AV6, 12BA6, 12BE6 was used in auto radios 1953 to 56-57 or
so. The 6AU6 is also a good possibility as early TV's were loaded with them
plus they got used in lots of non radio apps.

Back in the day 10,000 would have been a small run of one type. Non-amp
related trivia, but I wonder what was the most manufactured tube number? 12
or 6AU6, 12AX7, 5U4 etc?
