This gets at something I've been wondering about, on all b/w sets (atleast those using the same standard) I thought the frequency at the yoke coils for both horiz. and vert. and the number of lines on the screen always stay the same. So inorder to have a larger picture, something has to give, so is there more space between each line on a larger screen, are the lines thicker?
Secondly, inorder to increase the deflection angle, is the voltage at the yoke increased over what it would be on a set with a lesser deflection angle while maintaining the same frequency, or does it have more to do with the size/ shape of the yoke?
Thirdly, in the case of longer and shorter tubes, would not different distances between the gun and the front of the tube cause problems due to different amount of times it takes the beam to travel from one to the other?
I know if you increase the vert size, you're increasing the voltage at the vertical half of the yoke, but the frequency remains the same, now the picture covers a greater area and the deflection angle increased, but the number of lines is the same, so there must be more space between the lines. Also in some sense the vert. has to oscillate faster, because it now has to go between 2 higher voltages in the same time it used go between two lower voltages, this is why when you increase the vert. size alot the vert. goes out of sync?
And if I have absolutely no idea what I'm talking about, let me know.
