I recently bought a new (to me) equalizer and amp.
I bought the EQ from George and the amp from E-bay. The EQ is wonderful and was well packed, as was the amp. When I hooked them up the result was a happy Gidrah. The EQ did what was expected and the Soundcraftsman amp has plenty of power for my little bookshelfs. I also noticed that the Soundcraftsman is absolutely quite compared to the slight hiss of the previous the previous amp. Sorry Bob, but it looks like you'll be bridged and driving the sub when I build it.
The popping and screaching was probably from the bubble-wrap and styrofoam.:D
