Rob - It has been 35+ years since I worked for an Apple dealer, during the Macintosh announcement (and Apple sales, service training). I no longer have any of those documents. The Apple Community is extensive, and a quick Google search turned up many comments about Flyback, Damping Diode, & CRT replacements for early Macintosh. One individual acquired a replacement Flyback from Spain ($16 USD) for his Apple. Suggest you research those Apple owners for Mac specifications — possible replacement. https://macgui.com/news/article.php?t=446
