Apple II+ power supply woes

[adrianw@kay.st.nepean.uws.edu.au (Adrian Whichello)]

Hi Netland

I have an old 2+ which runs the model railway, among other things.
Last week it's power supply gave up. I wasn't there at the time,
I've found that leaving the computer permanently switched on is
good insurance - the power supplies tend to die between cycles if
eft off for long periods. Anyway, I opened it up and found that
an electrolytic had swelled up so much that it had torn it's connections
out of the circuit board. I replaced it, but all the power supply
wants to do now is go click click click ie it won't oscillate
properly. It does this if plugged into the motherboard or not.
Any suggestions about what else could be wrong. I'm not wild
about diving into a circuit that is connected directly to the
house supply without some clues.

Adrian.

ps surely this must be a FAQ by now - I have several old supplies
that are dead for one reason or another.
