Now I figure I might as well replace the amp tubes as well & get those two Chinese 6l6gc's out, but does the replacement pair need to be matched, or is that something that only pertains to separate amp heads?

Thanks for your help!
I assume it's a push pull amp so yes the 6l6s should be matched. sells them matched.
