An example is seen in certain Sylvania hybrid color chassis where both demodulator transistors have a 2 watt collector load resistor which chars progressively, eventially killing the transistor.

That set is why I said "rarely" go down. I remember well doing
them with a lot of burned up stuff & transistors that had the top or
side blown off. GE C-1 chassis had an 8.2K 2W in the video
that went way down but had little effect. Probably others I dont
remember now.......
