RE: I would not use wire-wound resistors in grid stopper positions

It's a question of Q. Will those devices exhibit sufficient dampening at the frequencies over which the tube exhibits a tendency toward instability? I've seen transmitting tubes oscillate when the carbon comps in anode suppressors (the second device you mentioned) were replaced with spiral-wound carbon film. Depending on the tube, the circuit and the physical layout, this can be a tricky thing.
