Another thing that some manufacturers did, although this would show on the parts list but not the circuit diagram, was to use 1/4 Watt resistors, which probably explains why I run into so many that have drifted upward in resistance over time in certain makes. In many tube circuits 1/4 Watt is just borderline, use at least a 1/2 Watt for replacement.
