This brightened is for the green gun so there is solid green and green and white the solid green goes to center of pot and the green and white goes to a resistor and soldered to one end of the pot and both go out to the tube.

This looks like it’s in series but I don’t see anything that ties in for extra voltage

I suspect it's on pins 4 ,13 or 5, depending on what ever color it was made for.

I found the basic patent with a schematic:
https://patents.google.com/patent/US4139861 The idea is to reduce the negative g1-cathode bias, increasing the current in the gun (but also ruining the lowlight tracking, which is then restored by adjusting the cutoff with the set's G2 controls). |

edit, Ahhh so my first thought was right!
Lower the cathode voltage a bit! :P

Ok so now we all have a better understanding of this anomaly device.

Of course, regardless of how it's done, it's like putting a band-aid on a gunshot wound, only will delay the inevitable, for a wile.

While it is a weird device it does work and it probably would work longer then a brightener that increases the heater voltage for that gun it’s being used for. Increasing the heater voltage creates more heat and would burn off more cathode material faster then if it were at the proper voltage. Just my thought on this.
