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?

After spending some time with a tube amp designer, I found that they will play with the bias voltage at times to achieve a "sound", sometimes at the expense of tube life. Ergo I would suggest that you find the voltage that the designer/manufacturer recommends.
