Contrast set too high on vintage sets.

Until fairly recently I would ALWAYS crank the contrast all the way up, and wondered why there was even an option. Threads like this on VK taught me the error of my ways!

Keep in mind that the early color sets that used the 21apx22 or the 21cpy22 had an orangey red color when the crt was driven hard and the brightness cranked up. If the set was adjusted with the proper black level and the contrast set in a normal range these sets can show an exceptional picture.
