Mike,
Although your advice is, as usual, superbly astute, and I know most experienced sparkies reading this thread will understand it, I know and understand that capacitance discharge can kill ya really quickly, I can only say that for the original question is to cut off and then let the capacitors self discharge for at least 12 hours before going anywhere them. The only answer is to cut the feed to all the transformers for at least 12 hours before servicing the stuff.
