Hi everyone! I'm new to this forum and was hoping someone could help..
I recently acquired an original Mac 128k in good condition but unfortunately does not turn on. I found a bit of corrosion on some of the traces on the analog board which I have cleaned up. I also found the fuse was blown on the analog board and the fuse holders both fell apart when I removed the fuse. The capacitors all look good, no leaking or bulging. I have now replaced the fuse holders and fuse (1.6A 250V slow blow) but unfortunately the fuse blows as soon as I turn it on Is this the correct fuse? This is what I removed so assume is correct..
Any idea what component/s could be faulty that would cause the fuse to blow? Is it worth replacing all the capacitors on these analog boards even if they look good?
The original owner said the Mac worked when they last used it about 10 years ago! He said he thought it may just need a PRAM battery fitted as this was taken out. I remember reading somewhere that these Mac's can still turn on without PRAM battery fitted, but may be wrong..
Any help would be greatly appreciated!
