Hickok 246 Bar Generator

[Electronic M]

Diagram is properly labeled.

If you mean mixing up the 3 grid leads it will just mean the gun killer color labeling will be similarly mixed up in use that way.

If you mean getting G1, G2, Cathodes leads mixed up.... G2 if you short it to ground will blank its color (G2 driver circuits could be damaged if the switch doesn't have a high enough built in resistance. If you short cathode to ground then the gun will be turned on more than the TV normally can it'll lharm the gun if operated that way for more than a few seconds, may harm the cathode drive circuits if let run like that long.

Most Delta gun sets would inject monochrome luminance monochrome video to the 3 cathodes, and R-Y to the red grid, G-Y to the green grid, and the same pattern for blue... The RGB video only existed in the electron stream as a result of grid and cathode signals adding. Around that time some Zeniths did it backwards Luminance on the grids and R-Y, G-Y, and B-Y on the cathodes.... Some other makes did it like that too depending on who the engineer was.
