    Dummy Load Heatsink

    I have some leftover 2-1/4" square 6061 aluminum and thought it would be good to make a couple of heatsinks for dummy loads. How does my design look? According to my CAD, I have ~.125m^2 of total surface area. I plan on using these resistors and fans. I figure I can connect the 2 blocks in...

    Dummy load for adjusting a Yamaha A-1 integrated

    Please could anyone direct me to the simplest and most economical way of using a dummy load to set the adjustments of bias and offset on an integrated amplifier? The service manual just say connect a "dummy load resistance (70W) to the speaker terminals." Searched but just can't find any visuals...

    Need help wiring a Dummy load

    I want to make a dummy load so I can work on equipment and not blow my eardrums out or wake up my kids late at night. I have two 8ohm 200 watt resistors that I mounted on heatsinks and put in a chasis. This works great and was easy to wire but I want to add a switch so that I can hear the sine...
