It seems to me changing the G2 on one gun could get the mid grays about right, but the tracking would be poor. I really would like to have seen one in operation.

Someone here years back had mentioned that some voltage is changed with this maybe how it’s wired like maybe the G2 The post is here somewhere but it was awhile ago. They still show up on eBay sometimes and this has a 7 meg pot and a high ohm resistor

Another thought is that if it's adjusting the cathode drives, since it's passive, it can only reduce them, so the correction would be at the expense of reduced brightness.

I do know with the red all but almost gone after plugging this in the red was really strong

I remember setting up this set and the red gun pot was maxed and bearly able to see the red that was there.

Well w/o seeing it, we can only guess at how it worked. :./

[timmy]

I have one for red and one for green but I don’t need either one thankfully.

Well, if you have 2, why not post detailed pix of them to help us understand how the work?

Do you mean take one apart ? The pic I posted just don’t show the pot

Yes, if available.
Also the one you posted is not very clear, it would help if it was higher definition, and all markings / words written on it could be seen to help ID it, cause it's kinda blurry and partial, looks like “Colorite” or something.
There are also other numbers on it, can't tell what they are, or if they mean anything at all.

This one is the same all three just got to get it apart

[Yamamaya42]

That thing seems to be a mystery device, can find no info on them at all, but lots on the normal heater type boosters.

[timmy]

This is odd it just looks like the pot and resistor is wired in series with the two green wires from the plug.

[timmy]

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

which ones on the socket??
