when changing tubes in the pre-amp section on a tube amp, do i have to replace every tube or can i just replace one and leave he others the same. what happens if i only change one and leave the others the same? will the sound be the same? or will i hear a minor difference?

Tell the friend that due to an amp explosion you are now temporarily deaf and will judge her friend solely on looks.
Good luck changing the tubes in your MG.

If you change one tube, change V1 (farthest right, looking at the back of the amp). That will have the biggest effect on tone. Without knowing what amp you're retubing, I cant tell you much else. It's usually good to replace them all at the same time, so that you don't have a few old ones and a few good ones.
