[QUOTE="Sarel.wagner, post: 1137720, member: 25509"] Since I now recently got the Analog Discovery I posted about above, it's time for a dedicated high dissipation, semi active dummy load. I have a dummy load in the Sencore Analyser but that is only really good for 50W. Otherwise I was using some unmounted resistors. This time the idea is to build a 4, 8 and 16 Ohm switchable, semi active cooling stereo pack, for at least 300 Watts at 8 Ohm and 600Watts for 4 and 16 Ohm. Will add Scope outputs later and a temp controlled fan for active cooling. First just the basics. Mounting the resistors on extruded ally tube and keeping the two channels isolated from each other. They will be vertically mounted on a fan base to actively cool em. The rotary switched will be used to select the various resistance or to switch to speaker out.
