i have a flawless one and it is a very decent boombox.
i also seem to remember there being the same model put out with yamaha on the case instead of yamaha.
down side of this fine boombox. phono line in. theres ways to get around that.
handle design is also dumb. sorry thats the only way i can describe it. too much sliding of plastic bits against metal bits on the handle.
battery holder design is also a bit odd.
they do have really nice sound. i liked mine a lot more than the pc11 i had but thats just me.
heavy. i like mine a lot good tape deck good radio nice speakers in mdf cabinets.
some of the last good sanyo stuff i think.
