Have I an explanation about? not for sure but now that the V-caps " disappeared " the hum gone with too.
Any explanation from some one of you? or an advise about?
" Now my experience is with Klipsch but I figure what crossover components do with them they do with others too. All the old Mylar caps in crossover 20 years+ old i have measured after removal have at a bare minimum .15 ESR and often higher than .5 ESR. New ones I use measure maybe .004 at the top end. It makes for some downright sour sounding speakers at times until you switch them out. Best bang for the buck upgrade on older speakers is recapping your crossover and you don't need silly expensive caps to sound really good.
