I'll rephrase the question ('hum bucking' coil)

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

My previous thread got off track (I apologize), so perhaps if I rephrase the question we can stay on track. Referring to figure 42 in the attached UTC catalog sheet, observe the 'hum bucking' coil and associated 1 uFd cap. Notice that the rectifier feeds pin 2 and that the cap connects to pin 1. What is the theory behind this configuration? How does it work/sound? It must not have been a huge commercial success, since only a few UTC chokes offered this configuration.
