ASTEC AA 11040B died while in normal use. Component at D9 which looks like a resister blew.
Apple Product Information on Astec Power Supplies, originator Larry Sovulewski from 1982 lists
D9 as a rectifier RGPA5B, I believe Apple part number 226-11100040.
Short of removing one from another P.S. where can I obtain one of these?
Thanks for the assistance
