The square ceramic 150 ohm 5w resistor on a 2230 power supply can scorch the C804 electrolytic capacitor and the wire running to the collector of the outboard transistor. It is squeezed in-between these two items (this does not apply to the units that have the resistor mounted underneath).
Is it OK to replace the square ceramic resistor with a more compact wire wound resistor such as this one?

I saw a post that described doing this, to increase the space between the resistor and the other components and provide for more air to flow between them. And I think it suggested a resistor like the Ohmite wire wound shown below. But I have not found the original post yet.
Is a wirewound is an appropriate resistor for this purpose?
