dummy load

Dumb question regarding using a dummy load while using a scope

I have recently acquired a scope and tone generator with the intent of learning to use them to trouble shoot some of my builds when I have issues

Any reason one should not use an attenuator dialed way down vs a purely resistive dummy load? I know its easy to build a dummy load but actually thought it might be beneficial to hear what is happening as well as see what is happening on the scope (and I already have a couple attenuators)

thanks!

One reason is when using a sine wave at the input--you do not want to hear what's happening then. Can you get silence with your attenuator?

[Lindz]

Yes it will turn it off (or so you can barely hear anything)

If the amp has a feedback circuit you really want a proper load on the output stage,as this is how manufactures test there amps and determine the voltages to lable there schematics with.

I use a THD hotplate set to off (silent) on occasion just for that.
