See http://en.wikipedia.org/wiki/Capacitors
The electrolytic type has a finite life - there's an electrolytic paste in them which dries out over a period of about 10-15 years (?) Incidentally I just started noticing a new type of capacitor, the "solid" type. (The first time I noticed them was in shots of the SB2 internals). The look like small metal cans - no plastic wrap or stress relief bends on top like the electolytics. Apparently they contain a conductive polymer. No liquid pastes to dry out, life estimates are in the ~25 year range. I'm not 100% sure, but they may also be smaller for a given capacity, although I haven't seen any really big capacity ones. -- Mark Lanctot "It's like, you know, a New Age religion, but with better treble response." - Jon Heal ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=32726 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
