Hi all, I messed up an SE/30 probably. At least I got it booting again, it has sound and video. But no ADB. Before I exchange the ADB Chip, can someone tell me is that silver thing the fuse? What is that black box? Do you think I can put in a different ADB Chip from another broken SE/30 board?

The silver thing is a fuse (the board has a marking for 'F1'). A simple continuity check with a multimeter ought to tell you if it has blown.
I had an ADB failure on an SE resulting from hot swapping a keyboard. It had shorted the circuit and blown that fuse.

Ok. Thank you! It seems to be just two pieces of metal kind of glued together. I heated it up and now it has continuity again. But maybe the first measurement was not valid. Do you know what the black box is? Is that to be replaced or only the chip?
This pad (pin 5) is deliberately not connected, so there should be no difference. The part at L1 is an inductor (coiled wire) and most certainly not in need of replacment.
And it‘s clear this is a n/c pad since there is no trace to it.
Btw you seldom repair such a board by replacing chips. Broken fuses, traces, solder joints or leaking capacitors are much more common. Let‘s hope you didn‘t do more damage to it.
