If I had to grade myself I'd only give myself a B. I used conventional solder whereas it would have been better to use solder paste I'm sure. The length of the new caps was greater than the diameter of the old caps so they only just fitted on the solder pads. If you look closely you'll see they don't quite line up perfectly. It was hard to get them to stay in place when soldering.
I just get a SE/30 with SimasiMac problem. I think that after some cleaning, especially if i doesn't solve the problem, I will replace the capacitors. Can you tell me what kind of capacitors you used? May be where you ordered them. Thanks.
