Video of set running

I finished recapping the set and made this quick video to show the set running, the color is actually a lot better on the set than it is in the video but the image is just too dark to be watchable in a normally lit room.
It looks okay in the video but the camera amplifies the light and it was taken in a dark room.

All the screen controls are full on as is the Kine Bias.
Is the 21FJP22 biased differently than the 21CYP22? I would think the CYP would be driven harder since it had less efficient Phosphors.

Other issues are getting the sound and image to work together and but I expect some alignment problems considering the coil swaps that were done, my main concern is why it's so dark.

I noticed with the admiral ctc-12 clone that if you tune the picture out to where you almost loose it completely it gets darker and the color level increases , if you yune back to normal its bright and if you turn back too far to where it just shows black and white it still is bright , so I go with the align the ifs then it might be ok , it might even be good to the point where you could use the rejuved crt if you care to.

No, it's just been sitting in the back bedroom, it works but not correctly, it just doesn't seem to have enough luminance.

Also I replaced the Chroma board and several of the crumbled coils on it so that needs an alignment also, something I'm not equipped to do.

Too many projects, not enough time or space.
