this kinda works ok,, still too much heat.
This is plumbing tubing slipped up inside a 500ohm resistor then custom formed on the ends to allow heat out.
it sits atop an aluminum wrap round shield to help wick heat to the air and to the chassis.

will have to resort to ordering something that is designed for 50watts or more.
I will likely get my new part and mount it to an aluminum fin block and then the aluminum block will mount in the same location as my fabricated 300ohm design shown in the picture.
Whatever i end up doing, this resistor is certainly not going inside the bottom of my chassis. it will be exterior mounted.

Radio works,, except for shortwave,, looking into that now,, just getting a hummmm at my temporary speaker.
