OK, the flyback is to the right, powered from 22 volts, and the yoke is across a capacitive voltage divider. Makes some sense now.
A saturable reactor is meant to saturate. A transformer wound (two separate windings) saturable reactor was used in some motor speed controls. A DC control winding would change the core saturation and thus control the transfer of AC power on the controlled windings.I can't remember seeing a single coil meant to saturate, just trying to understand what could be going on here.
I was making a wild guess that a magnet could bias the core flux so that the inductance could decrease with heavy current flow one way and not the other, thus expanding one side of the image. Never saw a circuit like that, and really don't know if that could be what's supposed to happen here.
Is there any kind of mechanical adjustment screw on the magnet of L503?
