Twentieth Anniversary Mac PSU Recap List

[daanvdl]

Hi everyone,

I recently recapped the power supply of my Twentieth Anniversary Macintosh (TAM), and I wanted to share the capacitor list in case it helps others working on the same project. I've attached an image showing both the capacitor locations on the PCB and a complete parts list with specs.

Hopefully, this makes the job a bit easier for fellow TAM owners. Feel free to share any feedback or additions!
Good luck with your restoration!

Oh perfect.. I’ve been meaning to do this for both of my TAMs! Did you also do the main machine?

 

[daanvdl]

Yes, will add this info lateron (Bose board / Powerboard / Logicboard)

would be good to include the original capacitor part numbers
