So, the caps I ordered are correct, but some numbering was incorrect. Also, certain ones HAVE to be a certain height, or they won’t fit under the CRT. Found that out the hard way.
Here is a question: I’ve been recalibration the brightness/contrast. On a “normal” one of these, does reducing the contrast all the way get you a black screen, or just an extremely dim picture? I ask because the cutoff control on mine moves with extremely gross movements. One click one way, and the highest contrast yields brightness on the black borders: too high. Once I get it set to where it looks right (none of that), there is still a dim picture of the screen at minimum contrast. If I adjust it where it is totally black at minimum contrast, maximal contrast is simply not bight enough for a CRT.
