I remember seeing B/W sets in the showrooms of department stores back in the day, and noticing the differences in the shading (color) of the CRT's on them.
We had a GE 19" set from around 1963 that was literally blue-white looking.

Maybe you have a 19AP4A or 19AP4B which have grey tinted/frosted faces ?

One good way to judge color is to stand back from the set in a dark room and see what the CRT is doing to illuminate the room. Is it bluish or greyish? The poor cameras are working overtime in a dark room trying to make something white...walls, lamps or the white Persian cat can all throw it off. Try taking a photo in a manual white balance set for cloudy...a higher kelvin temp closer to a CRT. This will fix the camera on a specific kelvin temp setting and you can then see what your CRT is doing in that neighborhood. It will also throw the surroundings very red as it tamps down the blue.
And on the sound IF tweek. Which is the best direction to adjust by ear? From the split to the end amp or backwards from the amp? And upper or lower adjustments first if the can has both? I did this with a Pilot TV-37 set to a good pix and had good luck going from the beginning to the amp.
