Please ignore my previous post, or better yet moderator please delete it. Here's a more refined version, with previous mistakes corrected, for a more thorough restoration:

I repaired one of my four AcBel API1PC36 MDD power converters, crudely but sufficiently, and in the process developed the following approach which replaces all but three life limited electrolytic capacitors with unlimited life MLC (Multi Layer Ceramic) or tantalum capacitors, or longer life PAE (Polymer Aluminum Electrolytic) capacitors, and minimizes new component ordering complexity by substantially consolidating...

I repaired one of my five MDD power converters, crudely but sufficiently, in the process developing the following approach which replaces many life limited electrolytic capacitors with unlimited life MLC (Multi Layer Ceramic) or tantalum capacitors, or longer life PAE (Polymer Aluminum Electrolytic) capacitors, and minimizes new component ordering complexity by substantially consolidating the range of values.

The consolidation is practical because none of these capacitors appear to be utilized in frequency or timing related circuits but rather only filtering roles, where more capacitance...

Hi everyone! Does anyone know where a schematic for this AcBel API1PC36 power converter can be found?

I'm currently troubleshooting three of these for personally owned Macintosh Mirror Door Drive systems but have no new significant insights to contribute toward the most common specific electrolytic capacitor component failures at this time. But I'll add my results when they arise.

I replace any relatively low voltage low capacity electrolytic capacitors with tantalum capacitors which of course provide the great advantage of being solid state and not inherently life limited....

Hi everyone! Many thanks for all your contributions - I'm very grateful for the considerable benefits your experiences provide. Due to overwhelming activity levels I'll probably be here only when specific needs arise, although since electrolytic capacitors are nearly the only life limited electronic components which plague modern electronics perhaps I'll use this site more often than many.

My complements to the design of this site - it's impressively thorough yet clean, elegant, and clear and thus quite easy to utilize.

I recreate primarily by restoring legacy cyber systems,...
