being so close to the designer, please ask him why only 1k

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??

Ok, I have to ask Why less than 10 ohm?

Output transformer would be the only way.

Ran across an article on using a 6U10 compactron 3 triode tube for an Aikido line stage. Has anyone tried this?

Isn't a fourth triode needed for the Aikido?

Schematic of Aikido line stage that you could use the 6U10 on.

There is a high gain section #2 in the 6U10 which could be used as the input tube once plate resistor and cathode resistor values were changed. Sections 1 and three would be used in place of the 12AU7.

...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...
