It's an SL-1500 with factory "S" arm. It came w/o a manual, looking up info on it I see a MK1, MK2, C and lots of SL-1200 info so it's a bit confusing for me although I haven't spent enough time yet to include reading the serial plate etc. I have a "low miles" Shure type iii and a Jico SAS I'd like to run on it, think the tonearm is medium compliance and the cart/stylus combo should work but again need to verify a lot. Might take you up on your offer if things are compatible thanks.
