SR Master Fuse and break-in

[Bill Demars]

I have a Synergistic Research Master fuse that I believe I need to break-in as it's quite edgy at the moment. I want to give it a fair chance. I am using a variac that has a fuse, where I am inserting the Master fuse, and am hooking up a fan to it. I have an all-tube system, so I don't want to have my amps and preamps on 24 hours a day. I am getting about .4 amps on my amps and watts plug-in device, with the fan on full-blast. Do you think this is enough and effective in burning in the fuse?

Agreed and same experience after 24 hours usage in my LPS, it's edgy and thin especially listen to brass or piano, not sure about how it may change but target to give a week since my lps is up and running for 24 hours, assume 200 hours is the maximum for the run in

Over 100 I find is the key milestone, with over 200 starting to really sing.
