Hi call or email BAT. They'll have the instructions they can send you. I used to have them, but long lost. I think you'll love the better tubes. It's a great phono stage!
It's not to hard and does make a difference when the bias is right...you will need a meter and a small plastic screwdriver, voltages are high inside there.
