A modulation transformer is an audio-frequency transformer that forms a major part of most AM transmitters. The primary winding of a modulation transformer is fed by an audio amplifier that has about 1/2 of the rated input power of the transmitter's final amplifier stage.

It’s the accepted way for high level AM modulation of the carrier. With 50% power of modulated final resulting in high level power output. Beyond 50% can cause clipping and distortion if the audio peaks are not controlled. The transformer in audio amp matches the audio impedance of the amp. The modulated B+ is then fed to the final amp.
Modulation Transformer Impedance Considerations
http://amfone.net/Amforum/index.php?topic=26630.0
With two tubes in push-pull, the total peak a.c. (audio) voltage across the primary of the modulation transformer is the sum of the peak voltages generated by each of the two tubes. If we assume the figure of 80% of the DC plate voltage, that means that the the total peak audio voltage developed by the modulator tubes cannot exceed 1.6 times ...

WARNING: The voltage across the capacitor, and also across the secondary of the modulation transformer can be several times the B+, under certain conditions, as described immediately below. There is an important (to take into account) series resonance effect that will occur in a modified Heising configuration at low audio modulation frequencies.
