Do I need matched tubes?

I have a Peavey Ultra 410...Been noticing some crackling in certain channels as of late so I checked the tubes... & yep I need some new ones.

I understand the pre-amp tubes are the cause of my particular problem so I'm just going to swap all four of those guys out & replace them with new 12ax7a/Ecc 83's. I'm planning on going with Sovtek 12AX7WA...They've been in there for as long as I can remember.

Now I figure I might as well replace the amp tubes as well & get those two Chinese 6l6gc's out especially cause the signs of wear are evident, I.e Brown print, but does the replacement pair need to be matched, or is that something that only pertains to separate amp heads? Or choice a choice of color...much like the endless debate of gold platted tips,high gain or soft gain tubes...

Thanks for your help!
