8 Ohm 100W Non-Inductive Dummy Load Resistor
8 Ohm 100W Non-Inductive Dummy Load Resistor is rated 4.7857 out of 5 by 14.
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!

Rated 4 out of 5 by from Good for bench testing more than just amplifiersI haven't used this to test my amplifiers yet, but it has worked well for testing a low power power supply - a +/-12VDC power supply. Hooking both outputs in series across the resistor dissipates 72W of continuous power (so watch out, it gets hot quickly!) but it gives a good idea of the power supply droop and ripple levels.

Rated 4 out of 5 by from Resistance is not futile...Great value. Nice package allows mounting to external heatsink and fan. Paid for itself with the first use.

Are these safe to use with solid state amps as well as tube?

2 dummy loads for stereo bench testing?

Do you need 1 dummy load for each channel when testing a stereo signal or can 1 load be hooked up to both channels at the same time?
Asked by: MeTarzan
You need two to test L & R at the same time. Connecting the two outputs together will cause either a failure or activate the protection circuitry [if your amplifier has one] and shut down.

Can add a plug and go directly into an amp?

If I soldered something likea Neutrik 1/4 plug (http://www.parts-express.com/pe/showdetl.cfm?partnumber=092-316) to the leads, can I safely plug into an amp as a load? Also is there a positive/negative side of this?
Asked by: Wesley23
Yes this is common practice when testing amplifiers. What is the reason for wanting to do this?

Is the power rating with or without additional heatsinking?

Asked by: whoaru99
Generally the ratings for resistors are the power ratings without additional heatsinking. With heatsinking you could safely put a bit more power through it, depending on how big the heatsink is and how well it is thermally attached to the resistor.
