Good evening all,
Tonight I accidently broke the CRT while removing the hard drive/floppy and I cracked it.
I have another spare CRT from Macintosh Classic, but it had different Yoke's connector.
SO I decided to swap over the yoke over to working CRT, but I haven't fired it up - I will resume working on it tomorrow.
Are there any step by step how to adjust the CRT properly by adjusting those magnetic deflectors knobs behind it if I need to?
Also, any good tutorials over it? That is Macintosh related would be bonus.
Cheers
AP

Thanks for that link.
Generally speaking, if one was swapping in a completely foreign, but compatible, monochromatic CRT, is the yoke orientation going to be the same, regardless of manufacturer?
I.e. if I'm swapping over an SE's yoke onto a not-orginally-Mac-9-inch-CRT, is it going to be oriented the same way? Flyback suction cup opposite of the analog board, the yoke positioned the same orientation.
Should I mark the yoke's orientation on my old CRT and line it up on the new one accordingly? So I shouldn't be worried about things getting mirrored/flipped? Sorry if these are no-brainer questions.
I know there will be some adjustment necessary post install but figured I'd ask the dummy questions 😉

The yoke always goes on the same way as it provides your deflection. if you put it on any other way, the picture would be wrong.
