I have an LM3875 in a case that I'm going to sell if I can get a reasonable offer. I am having such trouble finding a reasonably price pre-amp that I am seriously considering going back to an integrated or 2ch receiver. Serious enough that if the amp sells, I will. Any way, it was a fun project and I learned a ton but I'm not tied to it so... the amp is in a nice stainless steel enclosure that is in the range of 3"x12"x16 or 17" wide. It functions perfectly and I can provide exact details to a potential buyer as well as pictures. I'm seeking about $250 though reasonable offers will be entertained. Let me know if you are interested.
