Thought you all might get a kick out of this. This is my vintage Leach Phono Preamp still in the breadboard stage (yes - it looks like a mess). Sounds stinking good though. The Leach design was ok for what it was when it was published 38 years ago, but nothing great. That said it is amazing what some updated parts, additional filtering, and a dual mono implementation can do for sound. I have literally had these boards in storage for 38 years - just never got around to building them. I had two sets so made one a right channel and one a left channel with separate power supplies. Soon it will act as one of the inputs to my Pass DIY B1 Buffer (in progress). Very pleased with how it is turing out. Still to come: better signal wiring, better I/O jacks, and the removal of some now unneeded coupling caps. In the picture it is feeding the amp section of my 1250.
