If you apply a signal to an amplifier there will only be an output if the amplifier is powered up, connect a signal to the base terminal of a bipolar transistor and don’t connect the emitter and collector to a power supply nothing will happen. A transformer has never been and will never be classed as an amplifier! There is no signal input from the DC supplied control winding the input and output power in a transformer are AC. A thyristor can pass heavy currents between the anode and cathode when a small trigger signal is applied to the gate, the trigger signal isn’t amplified. The control winding in a magnetic amplifier is there to control output current, not to be amplifie. An amplified signal is identical to the input signal but bigger.
