i bought this system brand new about 15 yrs ago +/- yr or two. i have tried typing the model number i listed into search and nothing at all comes up in english but had 4 sites in foreign language display that model. All i basicall need manual for is the best setup or setup options. i bought entire set as a package but consist of receiver showing model number above, stereo tuner- ST-432; equilizer- EQ-432; Cd player/changer (has magazine type cartridge that will hold 6 disc-Cd-432;Dual cassette player-SD-432; its not old floor unit,when i purchased it, came with a black and glass stereo case,if any additional info is needed let me know, unit works perfectly well but connection have gotten all screwed up and i never properly marked things when disconnecting,really need setup guide to avoid potential problems.To me is does not look obsolete,has digital displays and unit is a brushed silver with easy touch smooth flat buttons ,only few knobs for bass and treble,everything else is buttons.I never thought it would be this hard to find a product that isn't "that" old. Please help, actually any info would be appreciated just to start me off in right directions
