They are different from the JC-2 or ML-1. As I recall the LNC-2 was designed by Dick Burwen, whereas the JC-2 was a John Curl design. Good luck in finding some, they have a cult following in Japan, so perhaps you might get some from a dealer there. What I would do is buy a Pass (my taste) outboard phono stage that has balanced outputs, as I recall the LNC-2 took balanced inputs (of some ilk) whereas the JC-2 was RCA. I don't know if Harmon would still make these modules up. Perhaps you can get in contact with Kim Catrell and see if she has any left over :)
