Default 6GU7 in an Aikido?

Just wondering if I could use 6GU7 in place of the 6Fq7 (input tube) in my Bas Aikido board. Would I have to change cathode resistors?

Thank you

I haven't been to his site in over a year. I found the article.

I tried the 6Gu7's without any circuit changes and they sound great.

You should increase Rk, though, if you use the 6GU7.

In my Aikido (240v B+) I use 470 ohm for the 6CG7 and 560 ohm for the 6GU7.
