IIRC it was completely impossible to find out about the exact builds that had the useless capacitors, as I couldn't find decent BOM which mentioned for which SER# it applies > And can I exchange these caps with > 'wire' (or a drop of tin myself? Yes, it's "easy" - you probably even can use silver varnish to short the capacitors. Just check the schematics and component placement, there are only 2 (symmetrical) 0R mentioned in earpiece patch, in series from amp to the transducer. You have to open a can to reach them IIRC. This also should be mentioned on hardware ML, and probably as well in wiki. /j
