I'm not so sure about that as upon crackin' the seal I found that a light alloy strip (heatsink I spose :laugh: ) had leaned over and shorted against a couple of other components. The smoke was just from a discoloured section of PCB around the base of those components which wasn't easy to find untill I removed the dust from it (too much dust maybe :?: ) and found that at least the pop sound was the fuse that they had at least thought to install in the unit (would've been much worse w/o that :eek: ).
