Twice Vcc in transformer coupled Class A amplifier AC load line
OK, here is a simple schematic of a transformer coupled amplifier;



Here are the voltages;



Notice before the sin starts the collector is at Vcc, 12V in this case.  This is because for DC the inductor is a short.  When the sin starts, it can only go as low as VE, which I decided to make about 2V.

The input voltage is multiplied by 100 so it can be seen, otherwise it would look like a flat line at 0V.

Here is the collector current;



I was trying to get the bias current to be 50mA.  This is close enough.
