6AQ5 headphone amp suggestion

[milen007]

I have 6aq5 lying around. I wonder if there is any good headphone amp design for this tube? I seen elekit have one but cant find any schematic.

Or i better go with other tube? Suggestion?

I would use transformer out as i want to drive 32ohm

Thx in advance

Et voilà. T1 should be 5k:32R... If there's not enough gain, drive it with a 6n1p.

6AQ5 is a mini 6V6. Look for a 6V6 plan and power it a little lower.

6AQ5 is pretty linear as it is. For a headphone, you can just connect it as a triode since you don't need 5 watts of power.

Electrically, 6AQ5, 6V6, 6P6S, and 6P1P are the same.
