Everyone of these guys gave you excellent ideas especially the WW non inductive resistors and getting selected low noise tubes..
As I looked at your phono module I had notice dip switches which Im assuming is for impeadance matching and you may have to experiemnt to get the best for your cartridge..If you have to the volume control up super high to get nominal volume,you have a mismatch and that can easily cause excessive hiss.
