this is from http://www.psaudio.com/article/39395/
I believe its a pretty standard circuit.
PS Audio made it very simple to get pcb and parts. designed to run on 9 volt batteries. I had ps laying around so I used it, running at 14vdc
Still breaking in and sound pretty good
this is MM only. I am using it with a SUT so gain is at minimum, loading 47k
chips are OPA2134 in first stage and LM4562 in 2nd stage
