Please note:

Power Supplies  We do not use the readily available low price capacitors that are in many cases counterfeit 

copies.  They often don’t meet the high temperature and low ESR specifications required for reliable operation 

in the switching power supplies as found in a vintage Mac.  Many of the 9” Macs have little or no fan cooling 

and the cheap capacitors will not survive this harsh environment very long.  We only use high quality name 

brand components that are sourced from authorized distributors and guaranteed not to be counterfeit. They 

are more expensive and often harder to get as most modern manufacturing has transitioned from through 

hole components as used in the Mac analog board to surface mounted components.

Logic Boards: We have switched to recapping the logic boards with Tantalum capacitors instead of the original 

Electrolytic type that had so many failures.  The Tantalum capacitors consist of a solid pellet and 

don’t contain the corrosive electrolyte that eats up the logic board when they fail and leak (and they do).  

Tantalum capacitors also offer very high reliability but you need to upgrade the voltage ratings over 

the original capacitors.  We are using 25 volt rated capacitors on the 5 and 12 volt circuits to give you 

that extra reliability.
