The solder joint at the lower left in the image linked below looks to be one with the resistor leg, bent over against the pad, and the solder floating on top -- resulting in the two wires touched together but not joined as "one", or, a marginal joint.
Images can be deceptive, but it wouldn't hurt to remove the solder from all the circled joints and do them again.
If not noise from the input connection or getting in the signal path through the unit, it might be some sort of instability in the power section.
