8 Ohm 200W Non-Inductive Dummy Load Resistor
8 Ohm 200W Non-Inductive Dummy Load Resistor is rated 4.5 out of 5 by 8.
Rated 4 out of 5 by from High Price, but obviously "Over-Built" by LMEM ChinaThese 200 watt resistors are Heavy for size. The extruded box section case is quite thick, with two 16 awg wires sticking out of the ceramic potting. Ink stamped info with the power and ohms info, a mfr ID and P/N. Googled "LMEM" and checked their catalog; they indeed specialize in resistors of this type. I am confident the value is there, but I ponder the reasons why these (Heavy) resistors are cheaper to IMPORT, rather than purchase from Ohmite or some other local firm.

Rated 4 out of 5 by from All very near 8.0 ohmsI bought four of these loads to create one LARGE 8 ohm LOAD, and two 4 ohms loads on the same 1/4" thick aluminum baseplate for a 200/200W stereo amp. They require a much larger heat sink fixture to handle/dissipate power for any length of time. You will need to DOUBLE the power capability for you amp, since the resistance of these loads will drift when they heat-up. Provide enough heatsink area with forced air cooling and they will work ok.

Rated 5 out of 5 by from Great ProductWhen working on my amps I can run a signal through it and save my ears can run amp wide open and check circuits without all the noise. Great tool for audio techs everywhere.

Rated 5 out of 5 by from Absolutely essential!Even though rated at 200W, a pair of these handled a 300W/ch amp at full power for well over an hour. Kept my coffee cup nice and hot too.

8 Ohm 200W Non-Inductive Dummy Load Resistor

This may be elementary, but do I just connect 1 end to the hot and 1 to the ground on a 1/4 input jack for the quiet recording?

Asked by: guitarboomer88
Yes. I just bought one for the same purpose. I'm going to use this instead of the more expensive alternatives with frequency response and pass through. It should soak up the power with one end to the signal and the other end to ground.It won't give frequency rolloff, but I'm not sure that will make much of a difference if you are just using your pre-amp output to record.

Two of these wired in parallel equal 4 ohms?

Can I wire two of these in parallel to create a 4 ohm load @400w?

Yes.

What's an appropriate heat sink?

I'm looking to build a 4 ohm 400 watt dummy load inside a case. Where might I locate appropriate heat sinks?
Asked by: psnyder
This dummy load already has its own heat sink built in. However, should you wish to exceed its power specification, it would be easiest to mount one or more 12V fans (readily available from Radio Shack) immediately adjacent to the dummy load. Adding additional finned heat sinks to the surface of the dummy load, coupled with silicone grease, as well as the cooling fans, could also be used for more, ahem, extreme applications.

So I could simply connect one of these to my guitar amp that won't exceed 120watts and I shouldn't ever have to worry about overheating?

Asked by: guitarboomer88
Overheating could still be an issue. Amplifiers are rated at a distortion threshold, not the maximum amount of power they make. A 120 watt amplifier can make much more power than 120 watts typically.

To be specific, I have a 100 watt solid state head and want to use the resistor as a dummy load with a di box for quiet recording, is this possible?

Asked by: guitarboomer88
That is indeed one of the applications this part is used for.
