8 Ohm 100W Non-Inductive Dummy Load Resistor
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?
How do I hook these up? Is there a schematic of this item? Thanks.
These are Dummy loads meant to connect across an amplifier to simulate a load. No polarity is observed.

just bought one.. can anyone please tell me how to hook it up? which wire do i attach ground to? just confused since theyre both the same, i know i have to somehow attach it to a ts cable. Please help!!!!

This is a similar question to someone else's but I want to be clear.... Can I use this WITH an existing speaker in a 1x12 combo amp simply to reduce wattage to the speaker? I would like to halve the wattage to the existing speaker while playing.
This will technically lower the output of the speaker, but simply turning the volume down on the amp will do the same thing and not waist power as heat through the resistor.

is this a cheaper alternative to a THD Power soak? I want to be able to run a 100 watt tube head without bringing a cabinet with me and go out form the direct out to a PA mixer I'm assuming I will need to solder this to a 1/4' jack as well?
In most cases the 8 ohm resistor will drop the volume by 3 db. The THD drops volume by 4db or more all the way to infinity. IMO, not really comparable let alone a cheaper alternative. As far as running the output of an amp directly into a mixer, you need more than a single 8 ohm resistor to get the voltage down to what the mixer wants, as well as getting the input and output impedance so that both the amp and mixer are happy campers.

Can I run this with an 8 ohm speaker to make a 16 ohm load on a tube guitar amp?
Unfortunately impedance does not work this way. You will have to use a single 16 ohm speaker or two 8 ohm speakers wire in series.
