RE: Resistor dissipation Question

This is just Ballparking-- but to add clarity-- that resistor that was designed to have a heat sink-- the 50 watter as the example-- I would rate it at 1 1/2 to 2 watts without the heat sink.

Chassis make poor heat sinks for a power resistor that is generaing a magnetic field. Why bolt this distortion generator onto/into your chassis?

The easy way is to use air-cooled power resistors that are already rated well above the wattage needed, and mount these floating-- under the chassis on stand-offs-- keeping them away from anything else.

Holes should be drilled into the chassis-- both below and above the resistors to allow air-cooling vertically. Mount the resistor either horizontally or at a slight angle.
