I am not familiar with the Apple /// Power supplies, but the following info
is good for most switching supplies. Most switcher problems are capacitor
related. The capacitors dry-up from heat and age and lose effectiveness.
The capacitors that are the #1 failure are the raw DC filters at input from
the AC line. These are the largest tubular devices in the power supply.
There are usually 2 of these with a value of 470 mf 200 volt or similar.
Changing these will usually clear up the problem.
