Need to replace your 18,000uf cap on your Williams power supply?


 

These 18,000uf 20v caps (big orange cap in picture below) are hard to find and if you do it will cost you lots. Read on for a simple solution for this problem.

 

 

All you need to do is get yourself 2 10,000uf (16v or higher) caps and connected them in parallel. Electrically this will add to 20,000uf which is more then enough for these old PS. In parallel I mean hooking the "-" side to the "-" side and do the same to the "+" side (+ to +) and then connect them to PS board just as you would any other cap.
