Have done the Aikido. 6922 and ECC81. Sounds great. I have little experience, only built 2 line stages with the usual topology(grounded cathode thing) but from the first song i knew this was another story, really impressed. I'm very happy and think John Broskie is a really nice guy.

I absolutely love this Aikido Line Stage/Headphone amp. 6N1P into 5867's, tube rectified GZ32.
An externally hosted image should be here but it was not working when we last tested it.

It sports dual outputs(not compete in this picture), one pair transformerless 600 ohms output impedance, the other pair of outputs through Sowter 8665's @75 ohms impedance. Either set of outputs can do headphones or preamp duty and at the same time.
Since this picture was taken, I've added a switchable NFB loop and the OTL outputs.

THANKS JOHN BROSKIE
