So I found this Sears SR 2100 Series BoomBox at a thrift store a few days ago, and what a find it was! I have to admit, the sound is excellent. It does not have any gauges on sound controls, so I am assuming it was not a 'top of the line' boombox for it's time. The sound on it seems to carry for miles, however. As for the tape deck, it works. The sound is rather muffled. I wonder if a new belt could fix this problem??
