Well it was my first try re-capping a classic Mac, and I started with the Classic II. I got my replacement tantalum caps from Trag in the Trading Post subforum here on 68kmla. He was kind enough to ship me 13 replacement capacitors:
47uF qty 3
10uF qty 8
1uF qty 2
I went to work using two (2) of Radio Shack's cheapest, 15W soldering irons. I've soldered some in the past, but I'm certainly not an expert. I heeded the advice I found in the Capacitor thread, and used paste flux to clean the soldering area well. It really made the difference. I had no problem with lifting pads. I would be uncomfortable using anything more than 15W irons for this delicate work. The most difficult part was getting into tight spaces with both irons, due to the proximity of the port connectors and other large, plastic items on the logic board very close to the capacitors. The 15W irons are physically smaller and thinner than larger irons, and enabled me to get into tight spaces without melting other parts by accident.
There is a certain amount of electrolyte fluid from the old leaking caps still on the board. I used rubbing alcohol and q-tips to clean most of it up, but the whole board could use a good clean. Any suggestions? I might try the old dishwasher trick, but I thought about trying circuit cleaner instead.

My Classic II also needs to be recapped, just waiting for Christmas break to come along so I have the time.
