Dodgy EngineerDodgy Engineer fans have not been eating well recently, so here's what I'm up to:
It's the front board of a Bose Wave Music System 3. Every SMD electrolytic capacitor in these goes bad, so shotgunning them is apparently the safest option when repairing.
All SMD electrolytics replaced with tantalums, and I've removed the amp chip for testing.
Only one I'm not sure about was a 22uF that was possibly nonpolar?? I've replaced it with a polar tantalum, so if something goes bang I'll know what's up
