My Dad pulled our original Macintosh Classic out of a closet and gave it to me last week. We thought it was sold at a yard sale but it turns out we still had it. After giving it a once over the logic board had some capacitor leakage but no real damage. The analog board was a mess with capacitor leakage. I pulled the caps, cleaned the board with IPA and a lot of Q-Tips but didn't completely wash it with warm soapy water or anything. I pulled all the caps and replaced them all with a kit from Console5 on both the analog board and logic board. I plugged everything in and fired it up and it sounded like the power supply was struggling to start and high voltage didn't quite kick in. As I went to check the voltages on the floppy connector the capacitor in CP2 started to blow it's guts out the top and the C8 capacitor on the logic board started to brown (replaced logic board caps with tantalums). Yes, I know I shouldn't have had the logic board plugged in.. I was over confident. Anyway, I have read on here that some other common components that have issues are "TDA4605, CNY17G, IRFBC40, DP3 and DP4 (1N4148)." so I've ordered those. I am not finding nearly as much troubleshooting info on the Classic as I did for my SE and Macintosh Plus with Larry Pina's book so any leads to follow would be appreciated.
