I know what a modulation transformer is.
I know what screen grid modulation is.
I know what Heising modulation is.
Hi,
A modulation reactor is a big, HV insulated audio choke used to feed
d.c. to the tube finals of a broadcast a.m. transmitter.
The modulation transformer itself is capacitively coupled
across the modulation reactor. This keeps
d.c. off the modulation transformer secondary windings,
to reduce risk of saturation.
