Colour Classic 400v snap-in cap

[Jon183]

Ordered a colour classic, just wondering if anyone knows what 330uF 400V replacement cap will fit and if its a snap-on.

Also wondering if anybody has any tips about dealing with a dead colour classic.

You can try these troubleshooting steps. Should be a good start.

From reading many forum posts, it seems that the Color Classic is just a difficult machine to get working. I recently repaired a dead Macintosh Color Classic. When I first opened the motherboard tray, I thought that it was missing ram SIMMS and a processor. After research, I realized that there was built-in ram (additional SIMMS can be added -hence the empty slots), and I was only missing an optional co-processor. When I plugged the Macintosh into the wall, flipped the switch and attempted to turn it on by pressing the keyboard's power button, nothing happened. I then cleaned and re-capped the entire motherboard. (The attached picture shows the analog board which probably does not need to have its capacitors replaced yet) This still did not fix the computer. The computer only turned on when I inserted a fresh PRAM battery. With a battery installed and the system re-capped, the computer booted instantly and began operating normally. It now turns on and off -operating reliably just as any other restored Macintosh does.

Had a read of that page on troubleshooting steps. Interesting about the PRAM battery, I only have one new one left and will have to buy more but the last one can be used in the colour classic. Since this is the most expensive machine I have purchased so far, I want to replace every electrolytic capacitor I can, including on the analog board. We will see what the machine's condition is on Friday.
