Got back to this today.
70 percent mains and outputs +/-1V but go to 75 percent and outputs would
swing up and down to (reduced but large ) rail voltages .
Someone must have plugged something they shouldntave in the external inputs.
1x BA4560 there, except for grounded pin3 and 5, all other pins were near
enough at +/-15 voltages
