Flyback compatibility

[Cinan]

Hi all, can I use a 157-0121 Flyback from a Macintosh Classic AB to replace a Flyback on a 512k AB ? Same screen Clinton 5144.

I think they changed the flyback with later Classic ABs and Classic II ABs, so it depends which one you've got. If its from an early Classic AB, you can use it in the 512k.

Are you definite it's the flyback you need to replace on your 512k?
