Title: Rare Vintage Apple Lisa / Macintosh XL Power Supply Unit (PSU) - Internal Inspection Done
Description:Up for sale is an incredibly rare, authentic original internal Power Supply Unit (PSU) removed from an Apple Lisa / Macintosh XL computer system.
Markings / Part Numbers: 825-4047-A / 620-6203D
INTERNAL INSPECTION & CONDITION:I have carefully opened the metal enclosure to inspect the internal physical condition for prospective buyers:- Main Circuit Board: Very clean, no signs of burnt traces or acid damage from leaks.- Large Electrolytic Capacitors ("Can" Type): In EXCELLENT cosmetic condition, perfectly flat tops, no bulging, and no visible leaks at the base.- RIFA Film Capacitors: Show typical aging cracks in the epoxy casing (standard for their age). They will need to be replaced (recapped) before plugging the unit into a wall outlet.
TESTING STATUS:UNTESTED / Sold AS-IS for professional restoration. To preserve the pristine condition of the board and due to the cracked RIFA capacitors, this unit has NOT been powered on. It is an amazing, clean baseline for a vintage Apple recap project.
