12AY7 reduce further to 50%. 12AU7 reduce to 80%. Though personally I have never substituted any of these for my AX7's.
"Matisse" preamp - 12AX7 12AT7
I'm using a Xindak XA3250, which is basically a clone of the Matisse circuit, with two 12AX7 tubes and two 12AT7 tubes. Problem is, the gain is so high that I can hardly turn the volume pot without the system being too loud for some late night listening.
Anyone know the best way to reduce the gain? I figure changing the 12AX7 tubes for another set of 12AT7 tubes would be a possibility....
