In Reply to: Tell us more about the PX4 and PX25.... posted by andy evans on October 14, 2021 at 02:00:54:
Going over the data sheet, the 300B has higher ratings, and comparable linearity. Plus it doesn't have the hard to find socket.And, the 300B didn't die out because it continued to be made through the 80s for replacement use in the AT&T telephone network, whereas the PX25 had a much shorter original production life.
The PX25 looks more comparable to the US type 50, than to the 300B in terms of performance.
What am I missing?
