DC does not >flow through capacitors. Talk about assholes! The original discussion was about "super-caps", and quite a bit of DC will flow through one (especially when warm). Nicads are actually a good replacement for super-caps in most filter applications-- cheaper and more readily available, much higher (effective) capacitance, but somewhat less reliable. -- David DiGiacomo, BRAG Systems Inc., San Mateo CA (415) 342-3963 (...decvax!ucbvax!hplabs!bragvax!david)
