I just recapped an old Quadra 660AV. Before a recap, the machine was dead, no chime, no video, just fan inside PSU was working. Old caps were leaking slightly, but there were no traces eaten off. I replaced all of them with SMD Tantalums (11x 47uF 16V and 2x 10uF 16V). Now the Quadra boots like it should, also the video is spot on, but there is no sound, even no chime. I triple checked my soldering work if everything is correctly soldered, and it is. I noticed that when you play a sound, it sometimes crackles in a speaker for a half a second, like something tries to put some sound out. On external speakers, the situation is the same.
Also the SEBASTIAN IC gets quite hot (cannot hold a finger on for more than a second) after a minute or two. Could this be the problem?
Any suggestions?
