You mentioned earlier that you replaced a 250 ma. fuse with a 200 ma one. Assuming this is a standard glass fuse, can you take a closeup pic of it showing clearly the opened element?

Just a W.A.G., but is there by chance a filter cap directly upstream of this fuse, which, if the cap were open, would pass a large ripple?

On rare occasions, I've seen a bad filter cap passing enuff ripple to smoke the resistor directly 'downstream' in the B+ line. But never seen a fuse blown from this condition before.
