NOS K7500 is too dark, screen pot on flyback glued down
Got one of those minty K7400s from Chad. This chassis is fresh out of the box, never been used.
When connected to my CRT the screen is too dark. Adjusting the brightness on the remote board isn't good enough. I can't adjust the screen on the flyback because it's glued down. Is there any particular reason why a sealed K7400 from the factory would have this pot glued down? Can I adjust this pot or should I leave it alone?
Is this perhaps a sign that my CRT is shot, or am I reading too much into this?
My previous chassis (K7100) worked and was bright, but it has blooming and hor size problems I could never fix - hence why I want to use this K7400.
Thanks,
Darren
EDIT: it's a K7400, not a K7500
