Crossover distortion and NFB

[ChrisGibboGibson]

One of the advantages of super-regen. is that it tends to self servo to
swinging just above and below the point of oscillation. Such designs have
two time constants in the self-squegging circuit. The short TC sets the
frequency of the sqegging action and the longer one rides along at the
point of oscillation.

IIRC:
In the one I made, the first transistor was a RF amplifier and also served
as the audio output amplifier. The second transistor was the regen stage.
The first stage is the one that provides almost all of the selectivity.
The second stage is basically sampling the RF at a 30KHz rate.

Is it coincidence that we have another thread along the same lines or has
something got mixed up in the threads ?

The same people, I'm sure, read both threads. This one was more about the
history and not the current use.
