[comp.sys.apple] Power Supply problem

   I seem to remember someone bringing up a problem like this once before,
so if the question is redundant, hopefully someone will be able to summarize
for me. The problem is; the power supply on my Apple 2e "buzzes" when I 
switch it on. I might have described it as a clicking noise, also. When it
does this, the light on my floppy comes on, and seems to be flashing in 
time with the buzzing of the power supply. The power indicator light inside
the computer does the same thing. When the power supply is plugged in and
turned on without being connected to the motherboard, it still buzzes. What
could be the problem? Luckily I was able to borrow a power supply temporarily,
but I don't want to risk killing this one too. The ole 2e has been through 
three power supplies now, all of them breaking within the last year. Any
suggestions other than "throw it away"?

It is very possible that the power supply, in it's old age, is less capable of
pulling enough current. If you run the Apple in your House, make sure the Air-c
onditioning is not pulling the current alonne. If there was a serious problem w
ith the supplly, it wouldn't work. The drive flashing, etc., indicates hardware
 problems linked to a lack of current.
