[Jukebox-list] electrolytic caps

[CASWELL CIVIL & LANDSCAPE]

Hi, Looking at recapping an amp for the first time and need some help.  My concern is with identifying the pos and neg on the electrolytic caps.  Some have no markings and others have a solid black line at one end.( I assume this is the neg end but would rather be safe than sorry)  The amp is out of a 148 trashy.  Any help would be appreciated.
