Put the heat sink compound on the resistor. That way you won't miss your mark and less mess. Use solid copper Romex wire instead of that stranded aluminum wire.
I built a dummy load using 6 x 16 ohm resistors. Switching yielded values of 16 ohms, 8 ohms, 5.33 ohms, 4 ohms, 3.33 ohms and 2.66 ohms. This proved very useful for testing power outputs and protection stages. Many 'audiophile' speakers dip low impedance and the low ohms setting was very useful for confirming current capability of output stages.
Lol. I wasn't monitoring it when the amplifier was on test. I left the room for 5 minutes and came back to the amp going in and out of protect and the smell of a wood fire bbq.
@@AstrosElectronicsLab Lmfao that is epic 🤣 lol I built a 2×100watt at 8 ohm and 200watt 4 ohm load on a cpu heatsink with a fan. Works good .. the one you built is definitely up to the task for 90% of the amps out there. Keep up the great work.
