I was running a an audio service company back then. The noisy transistor issue declined to a very small percentage of problems by the late '80s. Based on that, I would say the processes had improved sometime in the late '70s or early '80s.
This reminds me of the little round epoxy uA703 that was used so prolifically as an IF amp in the early '70s. I must have replaced thousands of them. The later metal-can versions didn't provide the same opportunities for profit. :)
