Dec 7, 2021 at 14:59 comment added Tom Thank you very much. I understand that now. Again, much appreciated!
Dec 7, 2021 at 14:58 comment added jonk @Tom It comes from the 190 mV minimum plus the 1 V peak signal value. The emitter resistor (1) will go from 190 mV across it to 2.190 V across it. The quiescent point is halfway between the two.
Dec 7, 2021 at 14:53 comment added Tom Guessing about 700mV for the base-emitter voltage, this means the base voltage for 𝑄1 is −15V+460mV+1.19V+700mV=−12.65V. - Please can you clarify where the 1.19V has come from? Maybe it is very simple, but I should ask rather than guess.
