Open cct. 330 Ω resistor in the PSU: obviously it's good that you've found a fault that fits the symptoms, but it does make me wonder how that failure came about - considering that the unit was working O.K. before storage. Just a thought: is the failed resistor a wire-wound? And if so, could it be that the damp had corroded the resistance wire where it joins the resistor body lead-out wires? A visual inspection - possibly with a magnifying glass - might reveal.
