Parts Express8 Ohm 100W Non-Inductive Dummy Load Resistor

good product

I bought this to test a 50 watt power supply. It did the job nicely, and at 50% of rated power it only got comfortably warm in about 30 seconds of testing.

Not too much to say about this. It works great as a dummy load when working on vintage gear. Perfect

I bought 4 to make a dual speaker dummy load. The resistors worked great. Would recommend!

Bought 6 of these total. Made a switchable dummy load . 4 8 and 16 ohm configuration. Definitely mount it to a heat sink if you're going to max ot the wattage. I have 6 mounted to and old stripped down automotive amp heat sink with a dc cooling fan. The right setup and I can run 150 watts into each one without problems. I can scope my repairs now without damaging my ears or an expensive vintage celestion. Very good quality.

The resistance is very close at about 8.3 ohms a piece. They seem to be built very well. I mounted them on 1/8 aluminum and added a heat sink. Bought all the parts on amazon.

I've got one of these bolted to the metal frame of my workbench and routinely use it while biasing guitar amps and measuring their RMS output. It never gets more than just very slightly warm. I just drilled and tapped two holes on the frame for the bolts and mounted it without any heatsink compound. I like that it has built-in leads, which makes for a clean installation and leaves no exposed connections to accidentally get shorted out.

I purchased 4 in order to be able to repair and adjust amplifiers that require 4 or 8 Ohm loads.Good precision:Resistance at 100 & 1kHz - R1:8.036, R2:8.003, R3:8.075, R4:8.020Resistance at 10kHz - R1:8.084, R2:8.052, R3:8.118, R4:8.071Make sure that you mount them on a big heat sink.
