Hi Myraj
What speakers do you have currently and also what tube amp?
I have KEF Q300 speakers that are 6 ohm nominal and I use the 4 ohm tap of my Jolida 502P. From what I've been told many speakers that report 6 ohm impedance will dip down to 4 or go above 6 Ohms. It's usually not a flat curve. You might want to check with the speaker manufacturer to confirm. You could use the 8 Ohm tap even. I think though your amp may run hotter. You should probably also talk to the maker of your amp to confirm as well. Good luck.
