I'm running my Akido pre with 4 6SN7 via tube rectifier, into a Pass F5 driving my Small Thor 4 Ohm speakers. Plenty of gain and superb clarity. No microphony (sp?) 2 feet from speaker! What's the problem again?

so does anyone have any idea of how to effectively modify the Aikido linestage for <10ohm output impedance??
Ran across an article on using a 6U10 compactron 3 triode tube for an Aikido line stage. Has anyone tried this?
...its because the SS amp I am intending to use with it, has an unbalanced input rating of 1K ohm, so for optimal performance, using 100/1 ratio, under 10 ohms would extract most performance...., according to the designer whom I emailed about this...
OK, I remember that schematic. Are there other triple triodes out there. preferably a triple 6SN7? Any quadruple triodes?

Hmmm, a 6C10 is a triple 12AX7...it would make for an interesting two tube Jadis JP200 preamp...
here is my aikido finally finished and feeling at home in a for what i think a nice cherry wood housing.
4*6sn7 2*250v w ct 38v drop across r17 (1500ohm) and janus shunt.
it is dead quiet with the pcb ground tied directly to earth from iec inlet.
the sound in combination with the moskido is magic, i have yet to hear a better combo and that is without burning in of the tubes of the aikido.

An externally hosted image should be here but it was not working when we last tested it.

You used a choke with the Janus? Care to explain how you wired it in there?
Did you hear the amp without the choke? If you did, dus it make any difference?

Bump!!! I might be wrong but you would repace R17 with a Choke? I have no idea how to calculate what size Choke you would need.
I have the same Octal Linestage and His looks like a Beast compared to mine.
there is no choke in here.
i like a bit of room in my amp 🙂 plus i had plenty of wood.
salvaged a cherrywood cabinet for the amp.

Then the obvious question is what is the transformer thingy on the lower left in your picture, and the square box above it?
