I owned an ARC LS1 for a number of years in the early 1990s. At one point I had a problem with it not coming out of mute. I tried having it repaired localy but eventually ended up sending it back to ARC. At that time ARC removed the values from the parts they used.
I think I still have my LS1 owners manual around somewhere. It may have the schematic but I doubt it has a parts list. I do remember that it was of no help when I was trying to have my LS1 fixed.
