Send a note to Pass and ask (check the Pass website for contact info). I don't think the Aleph series has adjustable biasing. Is this a mechanical buzz or some thing you hear through the speakers?
Aleph 5 - buzzing sound when hot?
I just acquired and Aleph 5, but I have noticed that as the amp gets progressively hotter (after say 3 to 4 hours) of use, the amp start to make a buziing sound, which gets progressively louder with time. Is this normal for Aleph amps and if not, any ideas what it could be \and what I should do about it? The sound is definitely from the amp and not through the speakers.
Thanks
