Carl,
Then it is not a clamping circuit, the gain changes as i had said all along, but it does not clamp the output to any set value.
So you see why you can not remove the 10k resistor and have it work the very same way? As i said several times, with the 10k resistor it is not a clamp, but without the 10k resistor it then becomes more of a clamp (10k shorted).
The new gain will vary from whatever 43k provides to whatever 43k in parallel with 10k will provide as the transistor conducts more and more. That's definitely not a clamping action, and it's not when the transistor saturates either. The output is free to rise more as the input signal level is increased.
I dont see how you can say there is any clamping action, that's what you are saying that i dont see, that's the only thing. Explain how the output goes to some set level and doesn't rise significantly (aside from running out of supply voltage of course).
