I should add. The cold/hot resistance change is much greater in the
NTC thermistor, which means that while it does a much better job of
limiting the initial inrush current, its resistance once it reaches
its final state will be only a few tens of milliohms, so it becomes
essentially invisible to the circuit in operation.
This would be a typical choice

The presence or not of an NTC in an *amplifier" has no effect on the behavior of a "dim bulb"at switch on.
I deal with this stuff *every day* and Don does NOT !!!
