where Sr1 - the dividing condenser between Rg and the first cascade, C12 - between the first and second cascade, C23 - between the second and third, C3 - between the terminal cascade and loading. Having put all other capacities on 479∙10-9F, we will provide recession, it is less than demanded.
Current of base is defined by Rb. At increase in current of a collector tension on Ukeo falls and therefore base current decreases, and it does not allow to increase further to collector current. But that base current began to change, tension of Ukeo has to change for 10-20%, that is Rk has to be very great that comes true only in low-power cascades.
