    I recently took my HK AVR630 to an HK service center after the front left channel suddenly went quiet. Not silent, but very quiet.

    They've fixed it under warranty (big sigh of relief there) and called me to say it was done. I asked the guy on the phone what was wrong with it and he said that they 'did a factory adjustment and rewound the bias'. We both had about as much idea as each other as to what a 'Bias' is or how one might 'rewind', or possibly 'rewire', such a thing.

    Can anybody translate?

    There might've been some miscommunication or misunderstanding with the person you spoke to and the person who actually did the repairs. My guess is that they might've replaced some parts and/or had to adjust the bias (current) to the transistors. If it happens again, get it fixed under warranty and sell it.

    The warranty will be up in six months, so it'd better hurry up. It's 18 months old.

    Actually, I guess it's only got five months, it was in the shop for 3 weeks.
