Does this amp have an Auto Bias circuit?

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

Can i connect a tuner on aux?

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

When your done listing to music, and you turn the a20 "off", are you suppose to turn it back "on" again for 5 minutes??

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.
