  Replacing an Apple III Power Supply by Bill Degnan - 10/24/2007 22:49
Received an Apple III not powering up.

Noticed that the fuse appeared to be blown. It's a 5mf 2 3/4 A fuse about 3/4" tall. Confirmed that this the correct fuse. Bought replacement fuse, that one popped too...must be a bad power supply...

I bought a replacement power supply from
http://www.vintagemicros.com and it worked. I highly recommend this site for Apple systems and parts.

Here are some pics of the working system.

I have another Apple /// that was given to me some years ago at the Trenton Computer Festival.
