I was being mislead by L & R on the overlay near the mixer/PA umbilical
ribbon CN1. L is the L ch and R is the quasi ground for the L ch, the R ch
comes in nowhere near it. Full signal L and R gets to the PA but only very
low level gets to the R ch PA pre-driver stage, in for some messy opampish
fault finding or false mute, if the power rails are ok.
