I remember someone suggesting rebuilding an ST-70 with all point-to-point wiring. Looking at ebay adds, I found this:

or item# 140142880114
I especially like the XLR connectors for inputs. These make for a sturdy cable.
P.S. I am typing this while listening to Heart: Little Queen on vinyl, through a refurbed stock PAS3 and ST-70.
