I had bought this unit as a whole Ta-AV621 system at P.C. richards and son. after my divorce in 1992. And this is one of the few things I still have and cherish. out of the wholw system the CD player which was a carosel w/5 cd's went bad. replaced with a 200 cd player by Sony. now the two floor standing speakers just went bad. the speakers themselves dried out. I need to replace them. don't know if repair or replace the whole speaker unit. everything else is just great....over twenty years old with constant use. I think I've gotten my monies worth.
