Power resistors in transistor-like packages
I happened to see Hitano (and others) who manufacture power resistors in transistor-like packages such as TO-220 or TO-247.
Digi-Key is one of those who stock such resistors. Have you ever seen equipment with such resistors? I think they would be easy to heatsink, especially when making a large load resistor that is easy to keep cool!

Can't say I've ever seen them, that I know of...

Re: Power resistors in transistor-like packages
The dummy load I built uses a few of them: http://badcaps.net/forum/showthread.php?t=8870 (about halfway down). I used them for that exact reason - they're very easy to mount to a heatsink.
