U1 is skewed. Soldering points are not original, it was probably re-soldered in the past. The upper four pins seem to have too few solder, the other ones have too much. I would de-solder it, clean the pads, and re-solder it properly.
So I am still trying to get this SOWT-24 running.
To remember, all Caps, power regulator and the crystal were removed when I got the card.
I replaced them all but its still not running. I tried in a Aztech and a Soundblaster 16. As far as I understood it should run without additional driver when selecting Waveblaster / General Midi output on port 300/330 in a game - correct?
- do I have consider the direction when mounting the crystal? I think it should not matter?
- can somebody confirm I have chosen the correct Caps? 16V, 10uF? I have no photo where I can see it on a reference card.
- is the power regulator 79L05 the right one? I am very unsure about this as the previous owner used the board for his soldering pratice and a 79L05 was still installed. But maybe he replaced it already with a wrong one?
I dont think the soldering of U1 or the black caps are the reason. They are looking good to me and connections seem to be fine.

I dont think the card is damaged. After closer inspection I noticed nearly all cards of this lot were used for "soldering practice". And I was able to repair all I tried by removing excessive solder...
Mabye I should open a new thread, not all will look here...
Thanks!
