I have bags of these I collected back in my teenage years that came out of radios. My point was that with an amplification factor of 100 and only 1.2 watts in dissipation it is not the best for low distortion high gain amps. They can start to sag. They are used in lots of radios like Drakes and Swans to mention a few.

Complete nonsense? This is an angry crowd.

5 tube radios used a variety of tubes, but not from the 12A family.
