[Boatanchors] Collins receiver xtals

[LARRY D GODEK]

I picked up a collins 75S3 receiver today at a yard sale of all places!.  Only thing wrong was that someone had pulled all the xtals out and put them in a plastic bag.  No manual with it so anyone know what xtal goes where?  I've checked my archives (file cabinets) and don't have anything on the newer 75S series receivers.  Like to put them back in place and see if this thing works or not.  Everything else appears to be there albeit a slight bit of accumulated dirt which has cleaned up fairly nicely.
