Well, it might be a better bet to pull the logic board (power supply board) from a good working SE and place it into the SE/30's chassis.
Okay, so they are interchangeable. That makes things easier.
Let me step back a bit. My initial thought of swapping the logic boards was born of the combination of this intermittent video glitch and the dimness of the display. I took the dimness to be a weakness of the CRT rather than a power supply issue. Is that a good assumption? If it is, then at some point I'll need to deal with replacing that as well, hence the thought that a logic board transplant would be easier, assuming one had the spare machine to transplant into.
CRT failure is less likely than video component failure. Adjustments can be made to the
height, width, focus and brightness of the picture with the controls on the analog board.
A badly damaged CRT shows a cast over the entire front of the tube, where a partly damaged CRT shows ghosts of the Apple Menu Bar and icons commonly used in an
"Always-On" machine.
These CRTs are also compatible with the ones from the Plus, SE and Classic / Classic II
provided you change the yokes as well.
