> Modern film resistors, either carbon or metal, are far more stable and
tolerant of heating. They are also smaller for a given dissipation.

That's true, where only their dissipation in free air is concerned, which
is the condition approached in solid state equipment. But we're trying to
use them in tube equipment which produces vast amounts of unexpelled heat.
These modern resistors are not designed for such an environment. Don't
skimp. Consider fitting a wattage rating higher than the original.
