8 Ohm 100W Non-Inductive Dummy Load Resistor
8 Ohm 100W Non-Inductive Dummy Load Resistor is rated 4.8235 out of 5 by 17.
Rated 5 out of 5 by from 8Ω 100W dummy loadsI bought these because I have two personal power amps I need to service. As service doesn't require driving either to clipping (except very briefly), I deemed 100W loads to be sufficient for these amps, which easily exceed 200Wrms/ch @ 8Ω. What I had not expected was the build quality, ease of heatsink mounting, and ease of connection with the terminated wires. I recommend these to anyone, they are excellent.

Rated 5 out of 5 by from 8 Ohm Dummy LoadLike it, works, solid wire vs. braided (don't bent it a lot. The 8 Ohm is actually 8.2/8.3. Did not receive my free catalog in the mail.

Rated 5 out of 5 by from Great for repairsI have used the dummy loads whilst repairing and testing a 25w per channel amplifier. Even at full load for the amp (25w), the loads didn't even get warm.Highly recommended for using during repairs to save possible damage to speakers if the repair goes wrong.

Rated 5 out of 5 by from GreatAllowed me to crack my 60 watt tube amp. I might go with a 200w load next time though because this thing started getting hot, but thats what it's supposed to do.

Rated 5 out of 5 by from Can use with Guitar ampsI have used this with a standard amplifier to run in mono and with guitar amps. Functions beautifully. With guitar amps, you can put a DI in between this and the power amp and have your own silent recording rig.Very useful, great value, and doesn't get too hot. Only wish it came pre-wired with a jack or was in a housing.

Rated 5 out of 5 by from These are perfect for amp diagnosis and repair!Using these to load the output for testing in the onlyway to go!

8 Ohm 100W Non-Inductive Dummy Load Resistor

i need a dummy load for my new 100w Mesa Dual Rectifier (2 tubes pulled, making it a 50w). can i add a pot inline and use as a basic attenuator, as well as silent load? if so, specific type of pot needed? if Parts-Express sells it, link please? thanks!

Asked by: dreamconduit

If I run two of these babies in series with a 120 watt 16 ohm vacuum tube load will it help dissipate the heat better? Mostly I just want to have ample headroom.

Asked by: Grim_z
At 16 ohm the load will be less and you'll have twice the heat dissipation surface.

can I run this for a live application what I want to do is run 2 8ohm cabs and have 2 of the 8 ohm dummy loads to give me the 2 ohm load for that chl on my pwr amp, do these work for that

Asked by: Lonny Terkay Band
that would not get you any more output. A dummy load will just take the extra power and waste it as heat. The amp will be working twice as hard, but you will still get the same sound output from the speakers.

Can I get 2 of these and wire them like I would speakers to get a 4 ohm load?

Asked by: floodstage
I just noticed that you have 4 ohm load resistors on your site so question answered!

To be clear, this allows a tube amp to be operated without speakers present, with the dummy load's two leads wired to the amp's speaker posts in place of those speakers. Correct?

Asked by: Chronic Iguana
It may not be safe with all tube amplifier output transformers but for the most part, yes, that would be the idea.

How do I hook these up? Is there a schematic of this item? Thanks.

Asked by: HighLandsBoy
These are Dummy loads meant to connect across an amplifier to simulate a load. No polarity is observed.
