Is it safe to "mute" a tube amp with a dummy headphone plug?

    I can get some surprisingly good sounds from the line out on my 5150iii and using a cab impulse. The louder the better... But would it be safe to "mute" the amp by plugging a guitar lead into the headphone jack so that I can crank it and monitor the affected signal through my interface (leaving the cab connected of course)?

    The amp mutes the speaker out when the headphone jack is engaged, which implies a built-in, internal load sink. So I don't see why that would be an issue.

    Or just plug a set of cheap headphones into it for a load and throw them into a drawer to hide the sound....

    I doubt the amp relies on the load of the headphones to work properly. But, you could plug in a lead with a small dummy load on it, like 600 ohms to simulate headphones. Doubt it is needed though.
