If you want to run the preamp with a higher volume setting, you need to reduce the gain in the power amp. This can be done by inserting a voltage divider before the amp's first stage. It may be as simple as putting a resistor between the input jack and the tube pin in place of an existing wire.
The exact specifics will depend on your amp.

Doing this has several advantages. For one thing, if you are picking up some hum or other noise in your interconnects, this will attenuate it.
