What is the general answer. Also carbon film versus metal film. From what I have read the metal film is more quiet and has tighter tolerances. Thanks

Metal film is the best for noise and also will not get noisy from moisture inclusion over time from heating and cooling.
They can also be had in very tight tolerance ranges.

With whatever resistor you are replacing if you go up 1/2 to 1 watt larger in size, that will make for even less noise and less resistance drift if or when they get hot.

Commonly used 5 watt Emitter resistors I like to increase up to 7 watt.

I only stock metal film resistors. They just hold up better. Tolerance is better, and they are more resistant to drifting with heat.

All your electrons are belong to us.
