The 2N3055 power transistor was introduced by the Radio Corporation of America (RCA) in the early 1960s. It was one of the first silicon power transistors, offered unrivalled second breakdown immunity and found many applications particularly in audio power amplifiers.

I want to have a bunch of such commercial famous power amplifier models and UK/US brand names made in the 1960s (only with quasi complementary output stages).
Thank you very much for your hints.
