hi c999,
What is load for that revised circuit, what does it drive into?
E

 

ericgibbs. The workload doesn't really interest me. The main thing is to stabilize the circuit.
Bordodynov. That is, in this way we force Q2 not to go into saturation, fix the BC transition under reverse voltage?

hi c999,
Has your tutor stated that the output load the amplifier is driving into, is of no interest.
If so, I find that misleading, one purpose of an amplifier is to use the output to drive a load of a given impedance.

I agree that the amount of load is important, but I'm not taking it into account right now.

Thus, both transistors are located at reverse displacements of collector junctions. You ask questions, but you are too lazy to simulate the scheme and look at it yourself. Or are you used to having everything chewed up for you?

 

I doubt if I am interpreting what is happening in the simulator correctly, so I ask again.

 

For example, it seems to me that there is too much blockage in the upper frequencies, there is also a need for positive feedback on the upper frequencies. Will it be possible to align the gain with them?

You're wrong. Read the educational literature so as not to make illiterate assumptions.

 

@Сергей999
You can use parallel dynamic load instead series transistor:
______
ADDED:
This is thermostable variant with gain = 4000, positive feedback (C3, R4, R5)
and with expanded frequency band:
