a) The 300B (or any of the 300-series tubes in any case)
weren't used in Telephoney.
Actually they were. I've scrapped out enough obsolete
telephone equipment to know that they were used for
output stages in drivers for long lines, and also as
voltage regulators in power supplies.
They were used in audio
recording and playback applications for moving pictures
- and again, 10%+ distortion in actual use was neither
unexpected nor unacceptable.
Ever hear of inverse feedback? The good news is that
Bell labs did, and applied it to their equipment.
Didn't the guy that invented inverse feedback work for
Bell, or am I confused?
The earliest papers I'm familiar with came out of Bell Labs.
