The flyback transformer (FBT), also called a 'line output transformer' (LOPT), is a special transformer which is used to generate high voltage (HV) signals at a relatively high frequency.
Thanks for the link, and the warnings about safety and price, guys! I've worked on High Voltage Systems before, but I think I'll wait for TomLee to chime in before making any final decisions.
Well, I'll just have to call a couple of EEs I know who've been involved in SERIOUS MacHackin' since the 128! [;)] ]'>

The Flyback is not a direct "Apple Replacement Part". The only thing close, would be the entire analog board as a service part. Any old stock has probably been depleted or recycled by now.
Additionally, since this is the main failure for these displays, most of the "bad" ones you'll come across have the exact same issue. The tube almost never goes bad, unless the display is dropped or otherwise damaged.
NoPro, I can probably source/or get a spec & source for the requisite parts . . .

. . . they may even have a usable analog board lying around! [:D] ]'>

Come to think of it, has anyone ever researched the availability of newer analog boards from other mfrs. This particular CRT had to have been used by several mfrs. One of their ABs might be of a usable size/shape etc. What was the last monitor mfd with this CRT? [;)] ]'>
