Question About Biasing KT66 Tubes


Hi,

I am attempting to bias a tube amp for the first time and cannot find much information on biasing KT66 tubes. My amp is a Antique Sound Labs AV25DT, and I biased the tubes to 550mv based on some random google searching I did, but I'm not confident that this is correct.

How do I know what to bias the tubes to?

Thx for the responses. I tried emailing ASL, but they did not reply. I am going to do some trial and error work to determine what sounds best and will report back.
