Clone II Plus power supply



I had a clone II Plus power supply for repair this week. 
It was tripping - change the switching transistor capacitor but it kept on
tripping. I did a blanket replacement of all other capacitors (about 12) and it
now works 100%. The cost was about US$6 so come on guys start getting familiar
with how to keep your power supplies going. In 30 years time Apples with the
original power supplies in them should be worth quite a lot.
All caps were tested with an ESR meter after removal. Only two passed the test,
just. So the clone power supplies didn't use very good quality components, most
were rated at 85 degrees Centigrade I used 105 and 125 rated caps to replace
them.
Please note that these caps are polarised so you must put them back in with the
negative pin in the negative hole on the pcb. Please also note that sometimes
the manufacturer makes a mistake when slikscreening the component placement
markingson the pcb so rather observe the polarity of the cap you are replacing
than relying on the silkscreen.
