The initial bias setting is made when the amp has been on for a few minutes, usually after a tube change etc, and with the bias set at its minimum setting. Once that setting has been made let the amp run for an hour or so to warm up sufficiently then go back an check/reset the bias to the factory recommended settings. Unless you have a bad tube(s) or a poor amp these last setting should remain stable for at least a few months. Good to watch bias, but no need to be anal about it. :-)
Tube Amp out of Bias-what does it sound like?
Just wondering, If you have a tube amp which is not biased properly, what effects on the sound quality would it have?
I have some amps which doing a bias adjustment is rather difficult, the amps work and are operational and may be close to correct bias, but wonder what the difference would be if all was 100% perfect.
