replacing tubes on amp.

Augoners,
hi guys,i need some advice on changing tubes. sine my BAT amp have 4 pairs of power tubes and 8 pairs of the little 6sn7.. the question is..it is hard to find 8 pairs of 6sn7 of the same kind in the used market..do i need to keep the same brand on all of the tubes? and can i switch 1 or 2 pairs at a time or do i have to switch everything at once?.would it improve the sound if i replace only 1 pair of tube at a time?thanks

I'm guessing this is a vk60 or vk75. The front two 6sn7's are the most critical. If you are strapped for a little cash, then replace these two first. They also need to be very low noise, preamp grade types of tubes.

Replacing all the tubes makes a diff, just those two upfront the most.

Albertporter has good advice above to.
