Figured I'd share with the group.
Awhile back Rex had a channel go out on his EMU 0404 sound card. Took a bit to get here, but I now have it to troubleshoot.
I haven't even powered it up yet, and can definitely see a problem. The output resistance on the good channel is around 50 ohms (guess that's "good" or to be expected), but it's not even 4 ohms on the bad channel.
Seems there are two tiny transistors of some sort near the output connector. One's reading "good", the other "bad". Question is... what kind of transistors are these (gotta find one methinks). All I see is "6KI" (or maybe "8KI".. ) written on them. Anyone (sam) heard of these little SMT beasties?
Quick to tshoot, but I hate waitin' for parts..
