An easy and inexpensive way is to put in a fixed value attenuator at the amp input. You can buy them or have a techie do it for you. Cheap commercial ones are made by Rothwell. I believe you can get different values. Cost about $60. They are fairly transparent. Worked for me when I needed to do that. BTW, you may also be able to use them between your source and pre-amp if you underlying problem is too much gain from your source.
"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....
