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

Carbon film resistors are LASER trimmed, with a spiral cut. The spiral's presence makes the part inductive, which is a negative in grid stopper service.

Carbon film resistors are what I recommend for plate stopper service. The current in the plate circuitry is substantial and CC noise is an issue. So, some inductance can't be avoided, but at least the non-metallic nature of the resistance element is retained.
