Rich,
Define "overheated." I bet that the temps most anode suppressor
resistors are see are in excess of what the manufacturer thought they'd
see. I believe that yes, a failure that happens gradually over time will
not be visibly seen. Someone correct me if I am wrong, but aren't carbon
comps very difficult to tell if they've been heat damaged?
Rather from my experience with oscillations, things happen rather
violently when an amplifier takes off. I would expect if an oscillation
destroyed it you'd have more than 400 Ohms resistance. I'd expect the
resistor to be blown open like has happend to me a couple of times.
