Apple III power suppy repair

A few months back.. I was lucky enough to have someone donate their Apple collection to me. I was very excited about a boxed Apple III Plus. After about two days of playing with it and creating a handful of bootable WAP user group disks for it, when deep in thought in the middle of a puzzle game.. Smoke started pouring out the back of the machine. I panicked, unplugged everything, then desperately tried to open the case as fast as possible to stop whatever was on fire. Smoke was still pouring out the case and I had never opened this thing before. Found the smoke coming from the power supply, awesome, only like a dozen screws to get that out.. Finally got it out did a damage assessment.

Found a blown capacitor. After doing some web searching on this, apparently everyone has this problem with this .22uf capacitor. Couldn’t find one locally, ordered 2 from Taiwan, waited three weeks, idiots sent the wrong parts. Searched again, found some in the US..

If you find this blog post and need this .22uf 250v X2 capacitor, here it is. Found lots of message board posts about this problem, all with dead links. Let’s see know long this one lives.

Anyway, got it and just replaced my dead and blown one. Fingers crossed.. Fired it up.. It’s alive!!

Sweet, Apple III back is action for about two dollars.. Ah yeah..
