Apple Macintosh Sweep/Power Supply board 603-0102. Compatible with Macintosh Plus, Mac 512K and the original Macintosh 128K. Dated 1986.
RIFA cap at C38 has been replaced. Now when powered on it makes a rapid tick-tick-tick sound. No chime; no video signal.
I believe it is repairable. According to Dead Mac Scrolls, may need capacitors replaced at C24, C25, C26, C29, C31. Barrel rectifier at CR20 appears already to have been replaced, but should be checked.
Includes cables for CRT and logic board, and foil thingy for where screws attach board to chassis.
Sold as-is for parts or repair.
