It's tough on amps to run them without loads.
As other have said...not a good practice.
Just disconnect one channel and see if the unloaded channel has any influence over the loaded side...might be interesting..
It is tough to design a good sounding amp and also consider no load scenarios. I have very nice sounding build with OPT sec feedback to the output cathodes. I inadvertently unloaded one side and the amp became an oscillator. I reacon that the oscillation was propagated to the loaded channel back though the Power Supply. Regardless, it was a wake up as far as design considerations;> )
