Thanks,
I think you've hit it. Last night the set made a couple of 'cracks', fizzed for about 20 minutes then went quiet. I live in an old stone house with walls some 17" thick. For the last two days the weather's been very hot but before that, we had a lot of rain. The hot weather begins to warm the damp stone; as it dries out it loses water vapor. Outside this disipates but the air in the room holds the damp. In the evening the sets mostly on and running warm but from around midnight onwards, it's off. As it cools, a little bit of moisture condenses on the back of the tube; maybe the charge held in the EHT supply attracts some of the very fine moisture in the air.........
So for now, my concerns that just like the old DECCA we might have another fire source ticking away in the corner have been calmed down (a bit).
