Ortencia,
You'll need to open up the case and remove the "mobo", aka Logic Board in Apple Computer terms. This is the circuit board on the very bottom of the SE/30. Once the logic board is removed, hold the board top side up. Look in the top right-hand corner of the logic board. You'll see a silver colored part near the numbers 12 and 13. That part is labeled "F1". That should be the fuse for the ADB ports. You can get replacements from http://www.mouser.com or http://www.digikey.com .
I'm not sure if they are "fast-acting" or "slow-blow", but the type you want to look for is "surface mount" (SMT) and has a rating of .500 mA (milliamps). I think the voltage going through the ADB ports is around 5 Vdc (Volts DC).
I hope this helps.

PS: If you need pics, I'll provide them to you via email, as I have an SE/30 logic board to reference from.
