Well, nothing devastating and, in hindsight, not even worth crying about at this point.
It was the pair of Kenwood Floor Speakers I mentioned earlier, a set of RCA (!) Bookshelf Speakers, and a Zenith Tube HDTV. With the discount, all would have been quite inexpensive. But as I am quickly learning as a Thrift Store groupie, better things are bound to be on the horizon...
...and they were! At another shop I found a pair of JBL 52T (aka JBL52TQX) bookshelf speakers. WOW. These little guys sound amazing! Very very little has been written about them (as far as I can tell), and they deserve more attention! The sound is so pure and crisp (and where the heck is that bass coming from?!?!?)....best $10 I've spent in quite some time. I had planned on using these as surrounds...but I'm SO impressed with how they sound, I'm going to have to give that plans some thought!
At any rate, i'm SO glad the other stuff was sold out at the first store....I would not have made the effort to go to the other store to find these.
On a side note, does anyone know how to remove paint speckles from a cloth grill? The JBL's are in great shape, except for some white paint specs!
