I had a question concerning the safety of running the Fryette 2/50/2 power amp in mono operation. Even though both the Fryette and my preamp are capable of running in stereo, for certain reasons I need to run it in mono. My preamp manufactuer was concerned that it could hurt the power amp if it doesn't have a load on the 2nd input. Is it okay to run this thing in mono or does it have to be run in stereo? I've tried reaching out to Fryette but haven't heard back. I figure maybe someone here could shed some light on this. Any help is much appreciated.
