A: It must have Auto Bias because there is no where to manually bias the tubes....Great amp for the money.

**Q: Can i connect a tuner on aux?**
A: The auxiliary and cd can be interchanged.  I connected a dac to my auxiliary to play from my computer.  So my answer is no harm in trying

**Q: When your done listing to music, and you turn the a20 "off",   are you suppose to turn it back "on" again for 5 minutes??**
A: Turning tubes off and then immediately back on can shorten the life of the tubes. Giving it a few minutes to cool back down before turning them back on is a good idea. That's what they're talking about.
