50W power resistors

50W power resistors for making dummy loads

I’ve added these power resistors by popular request. Use them for making a dummy load for your amplifiers. I’ve chosen two resistance values: 6.8 ohms (to suit an 8-ohm amplifier output) and 15-ohms (to suit a 16-ohm output). Both are rated at 50W, and are housed in a gold-coloured isolated aluminium heatsink. Mount them directly on the amplifier chassis, or in a separate metal box (if you’re creating an external dummy load).

Note: (April 2022: the Russian invasion of Ukraine and the sanctions have disrupted the global supply of valves. Therefore, only the version without valves is available until further notice.).
